Silicon Nitride Ceramic:
Ceramic parts are mechanical parts made of special ceramic materials through mixing, forming, sintering and processing.
The special ceramic materials mentioned may be oxide ceramics, nitride ceramics, boride ceramics, carbide ceramics, and the like.
As an inorganic non-metallic material, special ceramic materials have many properties that metal materials do not have, such as: high strength, high hardness, high modulus of elasticity, high temperature resistance, wear resistance, corrosion resistance, oxidation resistance, thermal shock resistance. . In addition, the current ceramic molding process has matured, and ceramic materials can be made into various non-standard shaped parts as needed, replacing metal parts as key parts. From the aerospace and military perspectives, the high-temperature performance of special ceramics can be used in the space shuttle's thermal insulation tiles, intercontinental missile warheads, and rocket nozzle components.
The civil range is also quite extensive, such as common engine combustion chambers, piston crowns, rotors, corrosion-resistant impellers, wear-resistant pipes, bearings, bushings, ball valves, seals, screws... many areas where metal parts can be replaced .
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.
