Silicon Nitride Ceramic:

A method for preparing a gas pressure sintered structural part ceramic by using silicon nitride as a raw material, which comprises the steps of mixing, pressing, cold isostatic pressing, sintering and post-processing, and the ceramic raw material is in weight percentage, including 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. Performance, can be widely used in areas with high material requirements, especially for high temperature ceramic bearings and ceramic turbine blades. Silicon nitride ceramics have high hardness, excellent resistance to acid and alkali corrosion, and self-lubricating properties. Therefore, silicon nitride ceramic balls can be used as bearing balls in combination with metal or bushings of the same material. Can be used in special environments; in addition, ceramic valve balls can be used in the field of oil fields, and its electrical insulation can also be made into insulating rings; and because of its high sintering temperature, it can work at high temperatures, so silicon nitride structural parts can As a high-temperature support material for high-tech fields; silicon nitride ceramic knives for industrial machine tools, etc.

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.
