Skoltech scientists found the way to synthesise material harder than tungsten carbide by 50%

Chemists from Russia and China have found the possibility to synthesise a new super-hard material that is harder than tungsten carbide by 50%. The material could be used in drilling, engineering, and other fields in the future.

«Scientists from Skoltech, under guidance of Professor Artem Oganov, used the evolutionary algorithm USPEX, developed by the latter, to predict a new material that can be synthesised at normal pressure and which can successfully compete with tungsten carbide on the two most important parameters: hardness and fracture toughness. Although the material is weaker than tungsten carbide in terms of crack resistance by 20%, it outperforms the competitor in hardness by 50%,» the report says.

The new material was a previously unknown substance — WB5, which can be easily obtained under normal conditions.
