Silicon nitride is a gray ceramic with high fracture toughness, excellent heat shock resistance, and relatively impenetrable properties to molten metals.Using these characteristics, it is applied to internal combustion engine parts such as automobile engine parts, welding machine blowpipe nozzles, etc., especially parts that need to be used in harsh environments such as overheating.With its high wear resistance and high mechanical strength, its applications in bearing roller parts, rotating shaft bearings and semiconductor production equipment spare parts are constantly expanding.
