THE DIAMOND OF PERIORITO MADE IN CHINA

Chinese researchers have succeeded. They synthesized the hexagonal diamond of one hundred microns scale. It is a material that is mainly in meteorites and is harder than the common diamond of the earth. The diamond of putting in China is unique in its kind. The study is in Nature magazine. It promises to redefine the limits of superdide materials, according to researchers, cited by Xinhua.

Graphite monochristal

The terrestrial diamond owes its reputation as the king of hardness to its carbon atoms arranged in a tetrahedral network. This makes it extremely hard and wear resistant. However, this structure presents a weakness. Certain planes can easily slide and move when applying strength, which limits its resistance. Therefore, scientists have focused their attention on another type of superdiamante with a more exquisite structure and higher properties. The hexagonal diamond.

Chinese researchers who participated in the published study innovatively proposed a method to transform graphite into a hexagonal diamond. It was made in high temperature controllable conditions, high pressure and quasi -hydrostatic conditions. They compressed and heated graphite monochristals to obtain a high purity hexagonal diamond.

The previous attempts to synthesize a hexagonal diamond were largely unsuccessful. It is due to the rigorous training requirements. In high temperature and high pressure conditions, the final result tends to be the formation of a cubic diamond and not of a hexagonal diamond.

Superduro material

Why was the success of the synthesis of a high purity hexagonal diamond by the Chinese research team? It is attributed to the choice of high -purity natural graphital monocrytals. Also to the use of high pressure X -ray observation to monitor changes in samples. This was explained by Yang Liuxiang, one of the authors of the article. He is a researcher at the Advanced Research Center in High Pressure Science and Technology, based in Beijing.

The scope diamond made in China can revolutionize its industrial uses. This study feels the methodological bases for future research on diamond materials. This hexagonal diamond synthesized is expected to open new ways for the development of superdon materials. It would also serve for high -end electronic devices.
