In 2020, Chang'e-5 brought back a new substance containing zirconium and tungsten! This new substance is not only mysterious, but also has the characteristics of appearing at night and disappearing during the day, which has aroused heated discussions among scientists and countries around the world. Want to know more secrets about this new substance? Let's look down!
New material brought back by Chang'e-5 in 2020
The Chang'e-5 mission is an endless stream of surprises, and since the return capsule of Chang'e-5 returned to Earth with space samples in 2023, it has been causing people to discuss space.
Not long ago, Chinese researchers also announced a big surprise, that is, in the samples brought back by Chang'e-5, a new substance was found to be extremely abundant.
This new substance is composed of two elements, zirconium and tungsten, and this is the first time that such a new substance has been discovered and has never been seen before.
Not only has this new substance never been found on Earth, but it also has an interesting feature that it only manifests at night and disappears during the day.
Although people have heard of zirconium and tungsten before, few people know their specific uses.
zirconium
In fact, the name zirconium may be familiar to girls, because zircon is a kind of rough jewelry, composed of zirconium aluminate, most of which are transparent and colorless, and occasionally show a slight blue or yellowish tinge.
Zirconium aluminate is not only used to make jewelry, but also to make a variety of industrial products, such as strong armor, missile and tank shells in the aerospace industry, and high-strength alloys for industrial production.
In fact, not only zircon has zirconium, the atomic number of zirconium in the periodic table of chemical elements is 40, and zirconium mainly exists in mineral form in nature, such as chromite, red zircon, zircon, etc.
In the development of human society, the application of zirconium has been very extensive, especially in the aerospace field, most of the shells of spacecraft, satellites and aircraft are zirconium alloys.
And many high-end cars will also use zirconium alloy as the body material to ensure the strength and corrosion resistance of the car.
And now human beings are not only satisfied with the use of zirconium on the earth, but also began to use zirconium alloy in the universe, and the shell of the return capsule of the manned spacecraft of the eastern powers is a special type of zirconium alloy.
From the above, we can also see that human beings have a very wide range of applications for zirconium alloys, which are almost ubiquitous in modern industrial society, and have broad development prospects.
wolfram
When it comes to tungsten, not so many people may know it, but when it comes to "tungsten lamp", I believe everyone knows it at once.
In China for a long time in the past, the electric bulb is basically the use of tungsten bulb, although now with the development of technology tungsten bulb has been gradually eliminated, but we also have to sigh tungsten bulb once brilliant.
Tungsten belongs to the transition metal element, its atomic number is 74, in the periodic table of chemical elements in the sixth period of the eighth group, it is a high density, high melting point, good thermoelectricity, stable chemical properties and other excellent properties of the metal.
In industrial production, tungsten mainly exists in the form of powders, chips, alloys, etc., and because tungsten has good high temperature resistance and high melting point characteristics, it can maintain good hardness and corrosion resistance at high temperatures.
Therefore, tungsten is also widely used in the manufacturing industry, and with the continuous improvement of people's requirements for material properties, higher requirements are also put forward for tungsten alloy materials.
For example, in the automotive industry, due to the complex driving environment and the large weight of the car itself, there is a need for auto parts to have better wear resistance and corrosion resistance.
Tungsten alloy can meet this requirement, and can also reduce the weight of the car itself and improve the overall performance of the car.
It can be seen that as a high melting point metal material, tungsten alloy also has a very wide range of application fields and plays a pivotal role in modern industrial production.
And these two seemingly unrelated elements have something in common in the new substance brought back by Chang'e-5, and a new alloy material will be produced.
New substances
Analysis of samples brought back by Chang'e-5 shows that the new substance contains two elements, zirconium and tungsten, and the ratio between the two is 1:1.
In other words, this new substance contains the most basic and simple structural methods of the two, and through a simple combination, a completely new substance is produced.
Through X-ray diffraction analysis, it is known that the new substance is amorphous and has no obvious crystalline diffraction peak.
This shows that this new substance is a new type of structure and has unique physical and chemical properties, which we can call a new material.
According to the current analysis, this new substance will also produce a new type of alloy material, and has a very broad application prospect.
Through sample analysis, it was found that the content of this new substance in the samples brought back by Chang'e-5 was 1 ton and 20.2 billion grams, and there were other accompanying existences.
At present, the scale of such content may be beyond what can be produced by laboratory and industrial means of production.
And according to the information that China has released several times so far, the eastern countries have not yet disclosed the specific composition and preparation method of this new substance.
This has made the whole world full of curiosity and yearning, and many countries have also expressed their desire to share this "space gift".
The battle for global space assets
It can be seen from the competition for resources between people on the earth how fierce and cruel the competition between people is in the case of scarce resources, and at present, countries around the world have a strong interest in space.
In any case, the resources on the earth are always limited, and the universe is infinitely vast and infinitely vast, and the resources that cannot be exploited and utilized on the earth may become very precious in space.
Therefore, it is natural that all countries hope to be able to get a piece of the pie and occupy more opportunities and advantageous positions in the development of space resources in the future.
China's impressive performance in space exploration in recent years has also aroused the vigilance of many countries in the battle for space assets.
Therefore, many countries have also increased their investment in the field of space, and are actively looking for cooperation and exchanges in space and even striving for resource sharing.
Therefore, although there is no military conflict or war in the real sense between the major powers of the East and the United States, there is fierce competition in the field of science and technology.
In addition, China has been launching manned spacecraft for manned lunar missions in recent years, and the United States is also actively preparing for manned lunar missions, and intends to land on Mars in 2025.
This will virtually elevate the space field to a whole new level, and the Eastern powers and the United States will inevitably be involved in the battle for space assets.
epilogue
Space exploration is always full of infinite surprises and unknowns, and the new materials brought back by Chang'e-5 in 2020 are even more amazing. Zirconium and tungsten are already two elements that have a wide range of applications on Earth, and the new substances they make up are showing even more possibilities. The battle for space assets has also shown the fierce global competition in the space field. What are your thoughts on these new discoveries and space exploration?
