The hardest known materials , diamond and cubic boron nitride, are thermodynamically stable only at high pressure and temperature. Chemical vapor deposition and sputtering have offered low‐pressure alternatives to the traditional synthetic methods and these techniques have recently been exploited for the production of new super‐hard materials such as boron carbonitride and carbon nitride, which could be harder than diamond.
