Silicon nitride ceramic processing related applications / uses
2019 09/16
The application of silicon nitride ceramics is mainly used in machinery, metallurgy, chemical, aerospace, semiconductor and other industries, as parts of certain equipment or products, and has achieved good expected results in recent years, along with manufacturing processes and test analysis. The development of technology, the reliability of silicon nitride ceramic products is constantly improving, so the application surface is constantly expanding. It is particularly commendable that silicon nitride ceramic engines are being developed and great progress has been made, which has become scientifically and technically The main contents of the world-famous applications are: (1) in the metallurgical industry, enamel, muffle furnace furnace, burner, heating body fixture, mold, aluminum liquid conduit, thermocouple temperature protection sleeve, aluminum electrolysis Components on thermal equipment such as tank linings (2) in the mechanical industry, high-speed turning tools, bearings, heat-treated supports for metal parts, rotor engine blades, gas turbine guide vanes and turbine blades, etc. (3) in the chemical industry Made of ball valve, pump body, seal ring, filter, heat exchanger component, fixed catalyst carrier, combustion boat, evaporating dish, etc. (4) in semiconductor, navigation Air, atomic energy and other industries used in the manufacture of switch circuit substrates, film capacitors, electrical insulators subjected to high temperature or temperature changes, radar radomes, missile tail nozzles, support and spacers in atomic reactors, carriers of nuclear fission materials (5) can be made into artificial joints in medical engineering (6) The silicon nitride all-ceramic engine being developed replaces the same type of metal engine
