How the Zergs were Made

Chapter 26 Titanium Skeleton

The basic framework is selected, and the next step is the selection of bone materials.

"Do you want to choose 'calcium'?"

The material of calcium is relatively light, and the straight-shell nautilus used as a design template also uses calcium as the main component.

If you choose calcium directly, there will be a lot less things to deal with at once.

The skeletal system is not something that can be accomplished overnight. The density, chemical activity, and difficulty of obtaining new materials need to be considered. If calcium is used as the bone material, these data can actually be directly applied to the design. Go to a lot of trouble to re-collect parameters.

After pondering for a while, Hogu dismissed the idea.

"No, the calcium can't meet my expected requirements. The hardness of calcium as a bone is too low. To ensure the protection, it is necessary to thicken the carapace. Meaningless."

The Mohs hardness of calcium is 1.75, and the Mohs hardness of skin is 1.5. By comparing them, you can intuitively see how 'soft' calcium is.

Why did the original earth creatures choose calcium as their skeleton?

There are many reasons, but Huogu's main explanation is that in terms of the difficulty of obtaining materials, the creatures on the earth finally chose calcium as the bone material.

In the early earth environment, there was a large amount of calcium carbonate, such as calcite and limestone, there is a large amount of calcium carbonate, and, in terms of preparation, calcium carbonate is very easy to separate calcium element.

However, what Huogu wants is performance, and what he wants is a strong and light enough material. It can rely on cells to achieve material processing at the molecular level. I dare not say anything else, but in terms of preparing elements, it can already throw Those chemical plants on the earth are several blocks away, and it doesn't need to worry about the problem of obtaining materials.

This can be seen from Huo Gu's reserve of various types of elemental quality.

"But if it's iron, won't it be too heavy?"

Such a picture emerged in Huogu's mind - a newly designed cell cluster that looks like a straight-shelled nautilus wanders in the sea, and then gets closer and closer to the bottom of the sea, and finally can only move in the sea against the seabed .

"No, no, no! What am I thinking, this won't work!"

"A very light material is needed, it has to be light enough..."

"That is to say, the density must be low. If the density is high, the mass in the unit space will naturally be large."

This time it is indeed beyond the scope of Huogu's knowledge. Its old profession is archaeological excavation, and its proficient knowledge fields are geology and biology, and it only stays at the high school level for mathematics, physics and chemistry.

This is still relatively ideal. Before Huogu became what he is now, he was already an old man in his sixtieth year. It has been decades since high school, and it is hard to say how much he can remember.

Suddenly, Huogu remembered what happened at the International Astronautical Center, an old friend who worked there once bragged to it about a metal—titanium.

"Titanium, that old Tang guy blew this metal into the sky in front of me back then, and he said that the first generation of space battleships on Earth must also use this kind of metal..."

"Tch, I'm not afraid of the wind flashing my tongue when I say this kind of thing. There's not even a space elevator yet. The International Space Station is only the size of a small grain of rice. It's also a space battleship. I haven't even touched one of the sides, so I know that in my kind Bragging in front of laymen, tossing about Mars excavation requires manned spaceflight..."

Thinking of this, Huo Gu couldn't let go of his resentment. It was precisely because he was old and his old bones couldn't bear the reaction force of the rocket boost that he was reduced to participating in remote command work at the International Astronautical Center.

Now that you have all conceived space battleships, then hurry up and build the space elevator! I really want to participate in the excavation of Mars in person! ——If there was a space elevator at that time, Hogu's old body would no longer be a hindrance to his journey to Mars.

After venting, Huogu also returned to his original calmness, and began to examine the metal 'titanium'.

"As an aerospace metal, there should be no doubt about its resistance to high temperature and pressure..."

"There is also quality. Because it is still rocket transportation, the material should be developed in the direction of 'light' as much as possible, which just meets my current needs."

"Well, let's decide on 'Titanium'."

However, Huo Gu didn't know much about this kind of metal. After all, he was a layman who only knew how to do archaeological excavations. He had little knowledge of both industry and aerospace materials.

But it doesn't matter, you can learn if you don't understand, there are real objects, or you can experiment as you want, it's just that it will take some time to explore.

After selecting the bone material, Huogu began to obtain information about 'titanium'.

First of all, whether this metal can exist stably on the planet where Hogu is now.

This is very important, even if the properties of titanium are very good in all aspects, but in an environment where it is very easy to react, it is useless, and there is no shell that can provide protection.

The method Huo Gu adopted was very simple and crude. He expelled a small part of the stored titanium metal from the cavity into the sea, and then observed it with the naked eye on the rhizome system.

The titanium metal in the ocean is entangled by a root. While preventing it from being washed away by the ocean current, it also undertakes the task of sensing temperature changes. Any chemical reaction will be accompanied by physical changes of heat absorption or heat release.

After confirming that there was no change, Huo Gu took back this part of the titanium metal, and created a cavity specially used for experiments on a section of the main root of the seabed.

The retrieved titanium metal was put into that cavity, and Huogu followed the periodic table of elements, transporting elements from hydrogen, helium, lithium, boron... into the experimental cavity one by one, and withdrawing the elements after confirming that there was no reaction, Inject new elements, and so on.

After the aqueous solution environment is over, I will try to use the air environment to repeat the experiment again to see the changes in the air environment... Then there are various gas pure gas experiments to see the changes in titanium metal in this environment... and then It is the change in strong acid or strong alkaline waters...

To use titanium metal, it is necessary to have a comprehensive understanding of titanium metal. These tests cannot be lacking or sloppy, and must be carried out seriously in order to obtain accurate data.

Of course, other things have not been left behind. Step by step experiments are cumbersome and time-consuming, so Huogu chose to solve other problems in the new design in parallel.

The next thing to do is to design, rationally use every inch of space inside the cone shell.

Huogu has not forgotten the original design criteria - to design individuals that can survive the super wave!
