How the Zergs were Made

Chapter 25: Titanium Bones

The basic framework is selected, and then the bone material is selected.

"Do you want to choose 'calcium'?"

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

If you choose calcium directly, there will be much less things to deal with.

Skeletal system is not something that can be achieved overnight. It needs to take into account the density, chemical activity, difficulty of acquisition, etc. of new materials. If you choose calcium as bone material, these data can actually be directly applied to the design, eliminating the trouble of re-collecting parameters.

After pondering for a while, Huo Gu gave up the idea.

"No, calcium does not meet my expectations. The hardness of calcium as a bone is too low. If you want to ensure protection, you need to thicken the shell. But in this way, not to mention occupying space, 'lighter material' is meaningless."

The Mohs hardness of calcium is 1.75, and the Mohs hardness of the skin is 1.5. In this way, we can intuitively see how soft calcium is.

Why did the earth's creatures choose calcium as their bones?

There are many reasons, but Huo Gu's main explanation for his tendency is that in terms of the difficulty of obtaining materials, the earth's organisms finally chose calcium as a bone material.

In the early earth environment, there were a large number of calcium carbonate, such as calcite and limestone, which had a large amount of calcium carbonate. Moreover, in terms of preparation, calcium carbonate was very easy to separate calcium.

However, what Huo Gu wants is performance, which is strong and light enough. It can rely on cells to process substances at the molecular level. I dare not say anything else, but in terms of preparing elements, it can be rid of those chemical factories on the earth several streets, and it does not need to worry about material acquisition.

This can be seen from the elemental of various types of elements of Huogu's reserve.

"But if it's iron, will it be too heavy?"

Such a picture emerged in Huo Gu's mind - a newly designed cell cluster similar to a straight-shelled nautilus wandered in the sea, then getting closer and closer to the bottom of the sea, and finally could only move in the sea against the seabed.

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

"A very light material is needed, which must be light enough..."

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

This time, it is indeed beyond the scope of Huo Gu's knowledge. Its old practice is archaeological excavation. Its knowledge fields are geology and biology, and it only stays at the high school level for mathematics, physics and chemical.

This is still ideal. Before Huo Gu became what he is now, he was already an old man. It has been decades since he was in high school. It's hard to say how much he still remembers.

Suddenly, Huo Gu remembered what happened when he was at the International Space Center. An old friend who worked there once boasted about a metal - titanium.

"Titanium, the old Tang guy blew this metal to the sky in front of me, and said that the first generation of the earth's space warship must also use this metal..."

"Well, I'm not afraid of the wind flashing my tongue when saying this. I don't even have a space elevator. The International Space Station is just a little bit of rice, and the space warship. Obviously, I didn't even touch a side. I know that I'm bragging in front of a layman like me. It's going to be manned to spaceflight to toss a Mars excavation..."

Thinking of this, Huo Gu's resentment was hard to dispel. At the beginning, it was because he was old and could not withstand the reaction force of rocket-assisted that he fell to the International Aerospace Center to participate in remote command.

Now that you have all imagined the space warship, build the space elevator quickly! 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 the resistance to Mars.

After venting, Huo Gu also returned to his original calmness and looked at the metal 'titanium'.

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

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

"Well, let's decide it's 'titanium'."

However, Huo Gu doesn't know much about this metal. After all, he is a layman who only knows archaeological excavations. He knows little about it in the field of industrial and aerospace materials.

But it doesn't matter. If you don't understand, you can learn. If there is a physical object, you can experiment as you want. It's nothing more than a time-consuming to explore.

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

First of all, whether this metal can be stable on the planet where Huogu is now.

This is very important. Even if all aspects of titanium have good attributes,is in an environment that makes it easy to react, which is in vain. It can't do anything that can provide protection.

The method used by Huo Gu is very simple and crude. He squeezes a small amount of titanium from the cavity into the ocean, and then observes it with the naked eye on the rhizome system.

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

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

The recovered titanium metal was put into the cavity. Huo Gu transported the elements into the experimental cavity one by one along the periodic table of elements from hydrogen, helium, lithium, boron... and so on. After confirming that there was no reaction, he extracted the elements and injected new elements, so on.

After the end of the aqueous solution environment, we will try to use the air environment to repeat the experiment again to see the changes in the air environment... Then there will be various gas pure gas experiments to see the changes in titanium in this environment... Then there will be changes in strong acid or strong alkali waters...

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

Of course, other aspects are naturally not left behind. Step-by-step experiments are a cumbersome and time-consuming thing, so Huo Gu chose to solve other problems in the new design in parallel.

The next step is to design and make reasonable use of every inch of space inside the cone shell.

Huo Gu did not forget the original design standard - to design an individual who can survive under the super wave!
