Silicon Nitride Ceramic:

The method for preparing a gas pressure sintered structural part ceramic by using silicon nitride as a raw material comprises the steps of mixing, pressing, cold isostatic pressing, sintering and post-processing, and the ceramic raw material comprises, in weight percentage, the following components: Si3N4: 80-90 %, Y2O3: 6-14%, α phase Al2O3: 1-5%, WC: 1-5%, TiC: 1-5%. The preparation method has the advantages of simple steps, convenient and convenient steps, stable preparation process and high production efficiency. The structural member ceramic prepared by the method has high hardness, high strength, high high temperature resistance, high voltage impact resistance and bending resistance. The performance can be widely used in the field of high material requirements. 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.

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.
