nano Silicon Nitride powder

详情

Si3N4 nano material offers lower sintering temperature, high mechanical strength,  good chemical stability or anti-corrosion and self lubricanting. As dispersion phase in nanoceramic composites, it increases the strength especially at high temperature with a lower friction surface toward improved overall performances of the composites. Its main parameters are in the following table. Purity: *7.***9% [O] <0.**1% free [Si] <0.4% APS: *0 nm SSA: **5 m2/g True density: 3.4 g/cm3 Bulk density: 0.*5 g/cm3 Crystal cell: amorphous Color:  White Shelf time: *4 months
