SUOYI Good Price High purity Silicon Nitride Powder for Ceramic
Silicon nitride is an inorganic material with the chemical formula Si3N4.It is an important structural ceramic material with high hardness, lubricity itself and resistance to abrasion as an atomic crystal; it resists oxidation at high temperatures. And it can also resist hot and cold shock, in the air heated to more than 1000 ºC, sharp cooling and then sharp heating, will not break. It is because the silicon nitride ceramics have such excellent characteristics, people often use it to manufacture bearings, gas turbine blades, mechanical sealing rings, permanent molds and other mechanical components. If the use of high-temperature resistant and not easy to heat transfer of silicon nitride ceramics to manufacture engine parts of the heating surface, not only can improve the quality of diesel engines, fuel savings, but also to improve thermal efficiency. China and the United States, Japan and other countries have developed such diesel engines.
