A team of scientists from two universities in China have synthesized a material harder than diamond in the laboratory. When carbon is subjected to extreme heat and pressure within the Earth, it can crystalize to form diamonds;

The synthetic hexagonal diamond exhibits high thermal stability up to 1,100°C and a hardness of 155 GPa, promising advancements in aerospace and defense industries.

A team of physicists, materials scientists and engineers affiliated with several institutions in China, working with a colleague from Umeå University, in Sweden, has grown a diamond that is harder than those found in nature.
