Audited Supplier Silicon nitride is an inorganic substance with the chemical formula Si3N4. It is an important structural ceramic material with high hardness, lubricity, wear resistance, atomic crystal, and oxidation resistance at high temperature. Moreover, it can also resist the shock of cold and heat. It can be heated to more than 1000 ºC in the air, and it will not be broken when it is rapidly cooled and then heated again. It is precisely because of the excellent properties of silicon nitride ceramics that people often use it to manufacture mechanical components such as bearings, gas turbine blades, mechanical seal rings, and permanent molds. If the heat-receiving surface of engine components is made of silicon nitride ceramics that are resistant to high temperature and difficult to transfer heat, it can not only improve the quality of diesel engines, save fuel, but also improve thermal efficiency. Such diesel engines have been developed in China, the United States, Japan and other countries.
Silicon nitride ceramic materials have high thermal stability, strong oxidation resistance and high dimensional accuracy of products. Since silicon nitride is a covalent compound with high bond strength and can form an oxide protective film in the air, it also has good chemical stability. It is oxidized, and is not infiltrated or corroded by many molten metals or alloys such as aluminum, lead, tin, silver, brass, nickel, etc., but can be corroded by molten liquids such as magnesium, nickel-chromium alloy, and stainless steel.
Silicon nitride ceramic materials can be used for high-temperature engineering components, advanced refractory materials in metallurgical industry, corrosion-resistant components and sealing components in chemical industry, and cutting tools and cutting tools in machining industry.
Since silicon nitride can form a strong bond with silicon carbide, aluminum oxide, thorium dioxide, boron nitride, etc., it can be used as a bonding material for modification with different ratios.
