boron carbide said - aziendaagricolabonellisergio

Boron carbide is very hard at 98 Ra, but it has a very complex lattice crystal structure. This structure results in weak planes inside the crystal, allowing failure and pullout to occur. Therefore, boron carbides mode of failure is some wear but mainly pullout of the crystals or parts of crystals. >> Ask price; Boron carbide | B4C - PubChem
