Product Description

black grey insulated Silicon Nitride Ceramic Bushing pipe

Reputation depends on quality, quality comes from Hard!


Silicon Nitride Ceramic:

1) Fabrication of components on thermal equipment such as crucibles, muffle furnaces, burners, heating fixtures, molds, aluminum conduits, thermocouple protection sleeves, aluminum electrolytic cell linings, etc. in the metallurgical industry.
(2) Production of high-speed turning tools, bearings, heat-treated supports for metal parts, rotor engine blades, gas turbine guide vanes and turbine blades in the mechanical manufacturing industry.
(3) Used in the chemical industry as ball valves, pump bodies, seal rings, filters, heat exchanger components and immobilized catalyst carriers, combustion boats, and evaporating dishes.
(4) In the semiconductor, aerospace, atomic energy industries, etc. used in the manufacture of switch circuit substrates, film capacitors, electrical insulators subject to high temperature or temperature changes, radar wire covers, missile tail nozzles, support members and spacers in atomic reactors, A carrier of nuclear fission material.
(5) Artificial joints can be used in the pharmaceutical industry.
The reaction-sintered silicon nitride is formed by forming a mixture of Si powder or Si powder and Si3N4 powder, pre-nitriding by nitrogen gas at about 1200 °C, and then mechanically processing into a desired piece, and finally performing final nitriding sintering at about 1400 °C. In this process, it is not necessary to add a sintering aid or the like, so the strength of the material at a high temperature is not significantly lowered. At the same time, the reaction-sintered silicon nitride has non-shrinkage characteristics, and can prepare components with complicated shapes. However, due to the low density of the product, the density is 70% to 90%, and a large number of pores exist, and the mechanical properties are greatly affected.
Si3N4 tube

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.
