Are aluminum oxide crystals difficult to get?
It’s not difficult, but it’s not difficult either.
It is difficult to say, because the current subjects have completely lost the memory of the industrial era and cannot leave it to their men to complete this work.
It's not difficult to say, it's because of the trumpet artifact seed in Wang Qi's hand.
Alumina was a research category of certain importance in the world of Wang Qi's previous life.
Wang Qi is not a chemistry major, but coincidentally, his career happened to be during the period when alumina was blooming in the construction industry.
Aluminum oxide is the main component of corundum and ruby/sapphire. Its alpha-type crystal becomes a substance with the luster of diamond glass after polishing. It has good mechanical, thermal, optical properties, and excellent corrosion resistance.
Most people cannot afford large crystals of pure alumina, and Wang Qi has only seen them when visiting factories. The price is scary, and it costs a lot of money to make small thin slices of sapphire glass for mobile phones. Generally sold alumina glass has an alumina content of less than 65%. It does not require such pure alumina powder, and the cost will naturally be reduced a lot.
But it doesn't matter, using artifact seeds to purify aluminum oxide is no more difficult than using it to directly produce mature iron ingots.
In order to obtain the magician's research support, he decided to make an exception and use the artifact seeds to purify the raw materials.
In fact, there are no other ways to contact the magician, but Wang Qi also has his own concerns. He is not sure how much of a threat the magician can pose to him and Li Xiang. Even if one or two people are lost through indirect contact, it can help determine the approximate number of people. How many attributes are needed to kill a mage?
Besides, the teacher has taught us that by uniting all forces that can be united and finding a common goal, cooperation will naturally be achieved.
Crystals in the name of magic are too expensive, which will inevitably lead to an increase in the threshold for magic applications, so start with them. Even if they are called magic stones or magic bricks, it will not hinder everyone's common goal of exploring the truth of magic.
Moreover, refining alumina is not just to win over mages, it is also a very useful material in itself.
Beta alumina is a high-quality adsorbent, similar to activated carbon. It is also called activated alumina. Its hydrate is the main source of industrially refined alumina. When mixed with natural impurities, it is called bauxite.
When beta alumina is heated, alpha alumina will be formed at around 1300 degrees. Depending on the proportion of completed crystal changes and the difference in state, it can be used to make crucibles, sapphire glass, abrasives, etc.
Wang Qi naturally wouldn't look for any bauxite, and would just extract it directly from porcelain clay.
As we all know, the main component of china clay is aluminum silicate, which is a hydrate of alumina and silica, and is also a natural mineral with a relatively high content of natural alumina.
It is not difficult to refine the artifact seeds using chemical preparation methods, because the properties of the two oxides are completely different. Silica is acidic, so the aluminum oxide can be dissolved directly with acid.
Biological organisms have extremely high tolerance to acidic ingredients such as hydrochloric acid. If you don't pursue yield, it is actually easier to operate than industrial production.
Wang Qi had two small seeds in his hand, which he usually didn't use, but he was prepared for them.
One seed still maintains the settings of the outpost, and the other has not been used and was originally intended to be used for extraction work.
This is not to predict the future, but to cope with the risk of war. If a hostile city or force appears and the iron plant's production capacity does not improve much, this stone will be planted to extract iron, manganese and other materials for use in making high-hardness steel. armed forces.
The prototype is here. Now it is easier to extract aluminum oxide instead of aluminum element. You can directly let the tree extract pure aluminum oxide hydrate, then heat it casually, and it will be dehydrated at more than 100 degrees and become alumina powder.
It took a few days to adjust the seeds and let Akeem, the original wild dog, go to the porcelain soil to plant them.
In fact, I wanted to leave the royal court and go out for fun, but there were too many things at hand and the destination was a little far away, so I couldn't make the trip.
In addition to his daily work, Wang Qi is also supporting the No. 2 furnace of the iron plant.
After summarizing experience through practical operations, the ironworks submitted the No. 2 furnace plan and a summary of their daily work.
It explained many things that Wang Qi did not understand. Based on this, it was logical to design a mature early industrial blast furnace.
It is known that in a real blast furnace, ore particles are thrown in from the top of the furnace and undergo oxygen removal and transformation before reaching the bottom of the furnace and dissolve into molten iron.
What Wang Qi had not understood before was issues such as furnace shutdown and restart, and the flow of slag during operation.
Limited by fuel types and production capacity, most serious blast furnaces will often shut down due to lack of fuel supply, but this cannot limit production capacity because the lower the production capacity, the higher the fuel consumption ratio.
The fluidity of slag mainly depends on the slag-forming agent. Wang Qi was completely confused in this regard and could only ask the iron factory to try various materials that could be found in the city.
There are many serious blacksmiths in the iron factory. Even if the memory of the industrial era has been completely lost, the lime is in the right place anyway, and it is not slow to add other things when there are more people.
The current furnaces burn multiple small crucibles at one time, and the iron consumption rate in the city is relatively limited, so one or two can be specially used for experiments. Even if the No. 2 furnace is started in the future, the No. 1 furnace will still take on some process experiment responsibilities.
This slag-forming agent is already effective. The iron factory has explored its own formula of co-solvent. The molten iron still needs a temperature of 1100 to 1200 degrees, but it is much lower than the previous furnace temperature. It is not a big problem. The furnace is made bigger. Higher, just provide a more adequate heating environment.
Wang Qi didn’t put too much thought into the plan for No. 2 Furnace, because No. 2 Furnace only adjusted the size, various pipes, feed inlets, and changed the tapping method, and the overall structural changes were limited.
What is more troublesome for Wang Qi is the supporting capabilities.
Once the No. 2 furnace is started, the production capacity will no longer be three to four tons. It will start at least dozens of tons per day, which is far beyond the long-distance transportation capacity of the caravan. We cannot let them rust in the warehouse. Or one day of production and one month of idle time.
There are only a few wild blacksmiths in the city, so how to consume so much iron ore has become a top priority.
It is impossible to gather all the blacksmiths and open one place, because the income of wild blacksmiths is too high. Many blacksmiths even earn more than Li Yunjie, the director of the iron factory. Even if there are no luxuries for them to enjoy, uu reading requires them to accept it sincerely. Lower wages are also a bit anti-human.
We still have to start with the iron factories and let them produce some semi-finished products directly.
Such as railroad tracks!
If you want to get rich, you must first build roads, not to mention other things. As long as a railway track is laid to the outpost, even if there is no power locomotive and just rely on human power on the railway track, the transportation capacity will be dozens of times higher than now. These transportation industry laborers can go Engage in other divisions of labor and create more product types.
Wang Qi has repeatedly considered that except for the rails, the production capacity of the No. 2 furnace cannot be fully consumed with the existing consumer production capacity.
Take the production of hammer heads as an example. Counting 300 grams each and a daily production capacity of 60 tons, 200,000 hammers will be produced in one day, and all citizens will have 1.6 hammers!
Not counting the time it takes to make various molds, everyone in the city can be equipped with all types of ironware in one month.
Of course, the quality produced by the existing production conditions may be poor, but the problem is not big. At this scale of production, the products will be shockingly cheap. The most expensive one is 50 cents. If it breaks, just buy it again.
It’s not that Wang Qi is unwilling to arm everyone with iron, but what are the conditions now, a purely manual iron-water pipeline? It’s really deadly!
There is also a large iron user who builds houses, and his situation is different.
For reinforced concrete, carburizing wrought iron can barely make usable steel bars. Anyway, it can enhance the strength of the building. The problem is that there is no concrete. There is no place to produce sand in the dark place. Even if you get cement, it will be useless. You can only use local concrete. And it is difficult to ensure that the steel bars will not rust. Once the steel bars rust, they will start to rust from the inside. Affects building strength.
So there is only railway track, which should be laid for 20 kilometers to the outpost first. If it is not possible, then it can be laid in all directions, to the porcelain clay production area and to Red Rock City. Anyway, there will be plenty of iron before the production capacity of the consumer end is built up.
