Boron carbide, alias black diamond, formula of B4C, usually is black powder.it is one of the hardest three known materials (the other two for diamond and cubic boron nitride), used to tanks armor, Body armor and many industrial products. Its mohs hardness is 9.3.
Boron carbide nozzle has the characteristics of more wear-resisting and high hardness, this meterial will gradually replace the known boron carbide nozzles carbide/tungsten carbide and silicon carbide, silicon nitride, alumina and zirconia material such as sand jet.
