Successfully combining super new nanomaterials

Researchers from the US and China, published in the Jan. 16 issue of the journal Nature, have successfully synthesized the new Cubic Boron Nitride (CBN) nanostructured material from Nitrite Bo (NB) cube.

The CBN , also known as Elbor, has a number of outstanding advantages, especially its hardness that goes beyond diamonds. That's why Elbor promises to be used in cutting special materials, as the best diamond cutting tools can not handle them.

Super CBN nanostructured materials

Research team led by Chinese physicist Tian Yuntszyunya has now tested the durability of the material. They said that in order to make Elbor deformed, a pressure of 108 GPa would be required, while the index of artificial diamond was 100 GPa.

Chinese physicists say Elbor is much cheaper than diamonds and can withstand temperatures up to 1,300 degrees Celsius in an oxygen-free environment. The high abrasion resistance and abrasion resistance of the materials indicate that they can be used as industrial abrasives or as coatings for cutting tools in the mining industry. ...

Built for the first time in 1950, the Bo-Nitride crystalline crystal has been used in a wide variety of engineering applications similar to diamond. This material has a thermal stability up to 1650 K compared with only 950 K of diamonds.

However, patients can not completely replace the diamond due to hardness of only half (50 GPa versus 100 GPa of diamond), so scientists used it to synthesize new hard materials. .
