New material harder than diamond

Researchers from Bayerisches Geoinstitut, Universitat Bayreuth, Germany, created a substance denser and less compressible than diamond. It was obteined by compressing fullerene (c60) molecules at a pressure of 10 GPa and a temperature of 2200 degrees Celsius. Attempts to measure the micro hardness failed, since a diamond indenter was unable to make a dent in the new material. The material however was able to scratch the surface of diamonds. It is beleved that the new material would be more effective than diamond for tools and other industrial uses.
