Silicon Nitride Ceramics Material
Silicon nitride ceramic is an inorganic material ceramic that does not shrink when sintered. Silicon nitride is very strong, especially hot pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density and high temperature resistance.
Silicon Nitride Ceramic are produced in 5 different ways, including SRBSN, GPSN, HPSN, HIP-SN and therefore have slightly different applications and working materials of these 5 productions methods, GPSN is most commonly used to produce silicon nitride components.
Silicon Nitride Ceramic 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.
Silicon Nitride Ceramics Applications
Machinery, electronic, semiconductor, chemical, petroleum, smelt.
Specific application: Welding shaft, electronic substrate, plunger, nozzle, slide guide, diesel parts, metal molding, shaft wheels etc.
Silicon Nitride Ceramic Rod
Silicon Nitride Ceramic Rod are commonly used ceramic materials in the metallurgical industry because of their uniform properties at high temperatures. Silicon Nitride Ceramic Rod Have excellent resistance to thermal shock due to their microstructure. The creep and oxidation resistance of Si3n4 is also excellent, and its low thermal conductivity and high abrasion resistance make it an excellent material to withstand the conditions of most industrial applications.
Ceramic Rod made of silicon nitride have a longer service life and can be used for long periods of time with high precision and accuracy. Metal rod pins often need to be replaced sereral times a day due to wear and slag adhesion. Ceramic rods made of silicon nitride, on the other hand, only need to be replaced about once a month because they do not wear our as quickly.
In most cased, the ceramic rods only need to be replaced if they are damaged by mechanical forces. This not only reduces costs and makes production more economical, but also stablized the entire process, resulting in a consistently high quality product.
