Reputation depends on quality, quality comes from Hard!
Silicon Nitride Ceramic:
Silicon nitride combined with silicon carbide is a high quality refractory material.
The silicon nitride-bonded silicon carbide material is added to the industrial silicon powder from the synthetic SiC aggregate. When Si and N2 react at 2N2+3Si→Si3N4 at high temperature, the SiC particles are tightly bonded to form a Si3N4 bonded SiC material. Therefore, Si3N4 combined with SiC has the inherent characteristics of SiC, is a high-quality refractory material, has high strength even at 1700 ° C, has creep resistance and chemical resistance, and has good heat conduction and strong wear resistance. . Therefore, Si3N4 combined with SiC material is more important than other combined SiC materials.
Silicon nitride bonded silicon carbide products have good thermal shock resistance, high temperature creep resistance, acid and alkali resistance, oxidation resistance, and resistance to molten metal corrosion such as aluminum, lead, tin, and zinc. Replacing traditional silicon carbide products with Si3N4 combined with SiC products can reduce the weight of kiln furniture by 50%, increase the loading rate of the furnace pool by 16%, and save energy by more than 25%. It is an ideal refractory material for enterprises to improve product quality and increase economic benefits.
properties:
High hardness, high strength, wear resistance, corrosion resistance, high temperature(1200°), good thermal diffusivity, good thermal shock resistance(avoid the temperature changing rapidly), good insulativity, low density. The comprehensive properties are best in most of structure ceramic.
