But for materials that are purportedly harder than diamond, using such relative criteria become problematic, which in turn raises the question of what it means — in quantitative terms — for a material to be harder than diamond. This question was the subject of intense debate amongst delegates ...
"We would like to find something harder than a diamond. If you could find other materials that are hard, potentially you could make them cheaper. They might also have useful properties that diamonds don't have. Maybe they will interact differently with heat or electricity, for example." ...
New material may be harder than diamond Researchers at Northwestern University's materials science and engineering laboratories have developed a new material that may be harder than diamond, the hardest known substance. Preliminary evidence indicates that a carbon nitride, 尾-... J Haggin - 《Chemica...

The other is to synthesize superhard materials with enhanced comprehensive performance (i.e., hardness, fracture toughness, and thermal stability), with the ambition of achieving materials harder than natural diamond. In this review, we present recent developments in both areas. The microscopic ...
Based on the analogy of the hardness differences between corresponding phases (α and β) of Si_3N_4 and SiC, it is predicted that α-C_3N_4 is harder than diamond (CC), whereas β-C_3N_4 is softer. Both phases of C_3N_4 could be more thermally stable than diamond. Hence, it ...

However, the intercalation of the smallest HDs with either mono- or divalent ions is estimated to give new nanocomposite materials which are harder than diamond.doi:10.1007/BF02451606G. BenedekE. GalvaniS. SanuinettiKluwer Academic PublishersIL Nuovo Cimento D...
