High quality nano silicon nitride powder Description
Silicon nitride has a number of valuable mechanical and physicochemical properties, which makes it a very versatile material. Bonding with silicon nitride significantly improves the performance properties of refractories such as silicon carbide, periclase and forsterite. Nitride bonded refractories demonstrate exceptional heat and wear resistance, as well as exceptional resistance to cracking, acids, alkalis, corrosive melts and metal vapors.
