Chapter 57: Titanium Alloy

x hundred wen! Xiao Jiu, collect the money."Zhao Ji immediately breathed a sigh of relief and quickly paid the bill.Although the amount of coins was more than Zhao Ji had expected, there was still a g..."Is this what you were looking for"

Li Yuyao asked.

Yang Lin shook his head, didn't explain, and still lay on the ground, carefully studying this black stone.

Though people didn't understand why these black stones scattered everywhere were worth looking at, they still patiently waited for Yang Lin.

Yang Lin was looking very seriously at it. He took a chisel and chipped off a small piece, carefully examining the fracture surface, and finally even tasted it.

"Bah!"

Tasting a sour and bitter flavor, Yang Lin immediately spat out the small black stone. However, his face became even more peculiar.

How is it going

Li Yuyao tilted her head, very curious.

Yang Lin nodded. “I recognize it, this is ilmenite!”

Because of the nature of biomineralization, it is not uncommon for coal and iron ore to coexist. However, it is less common to find ilmenite alongside coal seams.

"Titanium... ore"

Li Yuyao repeated those words, but she didn't understand them at all.

Yang Lin smiled wryly: "This is a very valuable mineral, but it's useless to us!"

Why

Valuable, but useless

Li Yuxiang can't understand.

"Hmm..."

Yang Lin pondered for a moment before speaking: "In simple terms, this ilmenite is rich in two elements, titanium and iron."

“Iron is worthless, there are many iron mines, even in the hills behind our house.”

But this titanium is very valuable! With this ore, you can refine a metal called titanium.

But the problem is...

"

We can't make it!

"

This is also the reason that makes Yang Lin laugh and cry.

He knows the value of titanium very well.

We can build airplanes and rockets!

Use it to refine alloys, its titanium alloy hardness is also very strong, and the anti-corrosion ability is super strong. Adding it to stainless steel can increase the corrosion resistance of stainless steel several times!

But the problem is what he said.

Don't come out!

Nowadays, metallurgy is so underdeveloped that it can't even smelt steel, let alone extract metal titanium from ilmenite.

And even if it could actually be refined, what use would it have

In the Great Qin dynasty, ordinary steel was already sufficient.

Even if we could truly forge titanium alloys, at most we would only create some dazzling divine weapons.

Let's go see the coal mine. of tofu know it well.Therefore, the cost of three-copper coins is not high, and the profit margin remains large; secondly, by fully controlling tofu production, in the future, one can produce as much...
