Zhu Youxiao's cheating this time was really successful, and after reading this periodic table, Bo Jue and Fang Yizhi both had a feeling of being stunned. After Zhu Youxiao started, they even found lead, tin and other orders that Zhu Youxiao couldn't remember clearly. Looking at their enthusiastic appearance, Zhu Youxiao smiled silently, maybe this is another opportunity to create a new situation, and these two may become a new generation of great scientists.

These two can be said to be a combination of two swords, Bo Jue's specialty lies in experimentation, and Fang Yizhi's specialty lies in thinking. Both of them are Song Yingxing's apprentices, and they are the right to use them for free. Song Yingxing's biggest headache now is that there will always be a certain error in the data of each test, and under Zhu Youxiao's narration, I understand that this is because of the excessive impurities in the material, especially when smelting special steel, it is the black ore that Zhu Youxiao asked him to add in steelmaking, although the quality of steel has improved a lot, but the quality is very unstable, which means that the content of the ore is not the same, so Song Yingxing asked the two to purify these ores, that is, to refine tungsten, which is a very complex problem. Let these two people have a hard time, because now they have no research on this ore at all.

Fortunately, Fang Yizhi is more intelligent, he found that the ranking of tungsten from the periodic table is relatively low, it should belong to a weak base or weak acid, and at this time Bo Jue has already produced hydrochloric acid, so that the direction of research can be opened from here, that is, each other's ideas are replaced step by step.

After Fang Yizhi discussed his research with Bo Jue, Bo Jue began to make a series of experiments to verify Fang Yizhi's ideas, and gradually this problem became a little eyebrow-raising.

Bo Jue first tried to use electrolysis to put wolframite ore powder with a fairly high tungsten content into water, and used graphite electrodes on both sides for electrolysis, but the result failed, because the ore powder was insoluble in water. The test with brine was repeated again, but the result was still a failure, and the method was abandoned after several consecutive attempts to solve the problem failed.

Next, Fang Yizhi suggested using caustic soda solution to try, and the tungsten ore powder was ground many times to get a very fine mineral powder, put it into the caustic soda solution, and then heated, when the temperature reached a certain height, the container began to dissolve, and after all were dissolved, the liquid was taken out, and the residue was discarded, and then the liquid was heated and neutralized with dilute hydrochloric acid, and then the liquid was discharged after cooking and concentration, leaving a solid substance for calcination, and finally the tungsten oxide was obtained, which was tungsten oxide.

After obtaining tungsten oxide, it is still crushed into extremely fine powder, and then continuously heated through hydrogen, until finally it all becomes silver-white crystalline powder. Although they endured a lot of hard work, they finally did it, and the two of them took this little silver-white heavy thing and sent it to Zhu Youxiao and Song Yingxing. These things are less than two catties in total, and this is the credit of the two of them consuming nearly a hundred catties of high-purity ore and spending a month.

Song Yingxing's reaction was relatively flat, but Zhu Youxiao was different, looking at these things and jumping up with joy, Song Yingxing didn't know why Zhu Youxiao was so happy, Zhu Youxiao only told him to sprinkle these tungsten powder into the molten steel evenly when the steelmaking melted, about two to ten percent, to see what difference the smelted steel was from others. In fact, Zhu Youxiao knew from the experience of collecting waste products that tungsten needs to use iron binders to better use tungsten on the steel base, which is the most economical material, but at this time, where to find those nickel and cobalt, I had to let Song Yingxing go to the experiment and add it directly to the molten steel.

Now that Song Yingxing has his own smelting laboratory, it is relatively easy to do this, anyway, there is no need to consider the cost now, Zhu Youxiao has money, so he will take these things to do experiments. After three days of hard fighting, Song Yingxing finally refined a small furnace of tungsten steel, which was made of Zhu Youxiao's method, and cast it into something like a drill bit and a knife, because Song Yingxing was afraid that it would become mature iron when refining, and there was too little tungsten powder, so he mixed a little coke into these tungsten powders, and as a result, carbon tungsten alloy steel was inadvertently produced, which greatly improved the hardness of the steel, and the sharpness.

When Song Yingxing used these alloy steel tools and drill bits, he knew why Zhu Youxiao was so happy that he was about to jump up, which was much easier to use than the original knives and drill bits, and was basically unaffected during long-term work. In Zhu Youxiao's view, these are the most basic things, and there is still a lot of difference from really playing the role of these metals, and the cost is too great, and it is best to use tungsten ore as raw materials in the future, but the content needs to be tested.

Zhu Youxiao believes that "people are divided into groups, and things are gathered by like", since Fang Yizhi has emerged, then it may not be impossible to find a few, and these smart guys can't learn those poems and words that have no value for economic development.

Zhu Youxiao summoned Fang Yizhi and asked him if he knew these guys, it was really good, under Zhu Youxiao's education strategy, these guys really didn't go to recruit flowers and grass, except for the one named Chen Zhenhui who went to the Daming Official Academy, and now he has gone to other places to be an official, and one of the "Four Sons" actually went to the Military Academy, Gu Yanwu, Huang Zongxi, Chen Zilong, these guys are all studying at the Daming Technical College.

After Fang Yizhi found these people, he went to Song Yingxing's house, Zhu Youxiao met these so-called celebrities in the late Ming Dynasty here, and through learning their ideals, he learned that under the guidance of his own idea of vigorously developing practical technology, not only the children of ordinary people came to the Daming Technical College, including the children of many official eunuchs also came here to receive fresh scientific and technological knowledge, Huang Zongxi's father was sent to other places to be an official, and he himself studied hard here, and now he is still a half-grown child. Gu Yanwu don't talk about this guy, he has always had lofty ideals, "The rise and fall of the world is the responsibility of the husband", this sentence, he is practicing now, but that is because he is young, he is studying, and he has not officially graduated.

Zhu Youxiao unceremoniously asked the four of them to form a small scientific research team at this time, Fang Yizhi became their team leader with his excellent organizational leadership skills, and put these extremely smart children under Song Yingxing's door, and let him give careful guidance, mainly to learn chemical knowledge, and they will be the backbone of Daming Chemical Industry in the future.

In addition to letting Song Yingxing directly accept these people as personal disciples, he also asked Xu Guangqi, Bi Maokang, Zhu Ling, etc. to guide them when they were fine, and he also worked hard to systematically recall some basic knowledge of natural knowledge, physics, and chemistry from elementary school to high school, and then wrote some textbooks suitable for children to learn, and let Xu Guangqi and Song Yingxing participate in the whole process, after all, they have all had the experience of editing these books in history.

Since he was able to find these people, Zhu Youxiao made up his mind to find and cultivate the famous guys in the future from now on, since they can leave their names in history, they must be momentary talents, as for some people who later surrendered to the Manchu Dynasty, these are all caused by the times, don't look at the three tiger generals under Mao Wenlong now, the later generations are all Manchu vassal king-level figures, and now they are all general-level guys, after all, those things are caused by the environment, don't think too much.

Zhu Youxiao patronized the matter of collecting talents, and Bo Jue has not seen a trace since he experimented with tungsten extraction, because Zhu Youxiao and Song Yingxing did not give him other test tasks, but he himself went to Bi Maokang to play. Here Bo Jue has a great interest in guns, whether it is machine guns, pistols, rifles, or hand-cranked machine guns, and then mortars, cannons, Bo Jue is not only interested in these things, but also has a very high talent, after a period of research, but also brought a great surprise to Zhu Youxiao, so that Zhu Youxiao can no longer worry about the research of weapons, Bo Jue's talent for weapons is almost no less than Bi Maokang, or even higher.
