Empress will not return to the palace tonight

Chapter 376 Knowledge Changes Everything

When Bai Yun saw that the emperor didn't speak, she was extremely satisfied.

From a chemical point of view, aluminum is easily oxidized, so aluminum exists in the state of alumina in nature, and it is not easy to turn bauxite into alumina.

The melting point of alumina is very high, about [-] degrees.

It is difficult to reach this melting point in the ancient smelting state, so the extraction is too difficult, resulting in very expensive pure aluminum.

Anyway, it is much more expensive than pure gold products.

Their Hou Mansion has a set of appliances made of pure aluminum, and their father and mother keep them as treasures, and only take them out from time to time.

How did Bai Yunyi get the aluminum powder?

In fact, it is obtained through a replacement reaction. Although it is difficult to heat metal sodium and anhydrous aluminum chloride together, it is much better than high-temperature smelting, which greatly reduces production costs, but it is still very expensive.

As for electrolytic aluminum?Then I dare not think about it, it needs a strong current to support it, and it is almost impossible to make such a thing in this era.

She only knows the principle and has not tried it.

If you can succeed, you will earn big.

It's a pity that I can only think about it now.

For the current Bai Yunyi, selling some thermite to the emperor is nothing more than a trivial matter, and getting some aluminum products to sell by himself will definitely make a lot of money.

Knowledge really changes everything.

Bai Yun couldn't help sighing in her heart.

However, she only achieved something by standing on the shoulders of those seniors in her previous life.

In short... She is very satisfied with her current situation.

When the emperor saw Bai Yun standing aside and giggling, drooling, he knew that this girl was having a sweet dream.

What he didn't know was that he was also giggling along.

The emperor wanted to hang on like before, but Bai Yunyi forcibly pushed him out.

Is the emperor lost in his heart?
That was impossible, because it made him more motivated to fight.

I have to arrange it quickly and speed up the process, so that I can marry my woman back earlier.

The emperor had just stepped out of the Ruihua courtyard, and was about to ask Zhong He to leave together, but found Zhong He and Jiang Heng standing at the gate of the courtyard staring wide-eyed.

"Jiang Heng?" The emperor was a little uncertain. After all, he hadn't seen that kid for more than ten years. When he left, Jiang Heng was only seven or eight years old.

"Eldest brother..." Jiang Heng recognized the emperor at a glance, after all, the emperor has not changed much in these years.

"Why are you here?" the emperor asked in surprise.

"I... I'm Bai Yunyi's bodyguard, why did senior brother come out of it?" Jiang Heng asked in great surprise.

"I want to talk to her about something." The emperor smiled.

Then the pair of brothers came to the side and chatted.

Jiang Heng is not afraid of the emperor at all, he only regards him as his senior brother, and the emperor is also very "loving" in front of his little junior brother.

After the two talked for a long time, the emperor asked Jiang Heng to go back to Cangyunzong, but Jiang Heng was unwilling. The emperor asked him to enter the palace and stay by his side, and then go back after his master and his wife came back, but Jiang Heng was also unwilling.

"I'd better stay here as a guard, I signed the contract." Jiang Heng laughed.

The emperor was slightly taken aback after hearing this, but this is Bai Yunyi's style, he has to sign a contract for everything.

"Okay." The emperor nodded slightly.

His family, Yun, is very good, and he will definitely not bully Jiang Heng. Jiang Heng will not be tricked if he stays here, because Bai Yun is very good to his family, and the emperor is at ease.
