With a Vickers hardness of >30 GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond. The particle size, particle size distribution and crystalline purity of the starting powder were examined Spark plasma sintering parameters - temperature, pressure and dwell time were varied. Wurtzite-like, wurtzite boron nitride has recently announced as a material harder than diamond. Such "recentness" is explained by the fact that it is relatively rare in nature, and these comparisons have practically not been made earlier. Boron Carbide - Applications - Price. By Paola Ayala.
