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, cutting tools and cutting tools in machining industry, etc.
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.
In addition, silicon nitride can also be used in solar cells. After the silicon nitride film is coated by PECVD method, it can not only be used as an anti-reflection film to reduce the reflection of incident light, but also, during the deposition process of the silicon nitride film, the hydrogen atoms of the reaction product enter the silicon nitride film and the silicon wafer, Played the role of passivation defects. The atomic ratio of silicon nitride to silicon nitride here is not strictly 4:3, but fluctuates within a certain range according to different process conditions, and the physical properties of the film corresponding to different atomic ratios are different.
For ultra-high temperature gas turbines, aircraft engines, electric furnaces, etc.

Silicon carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Coarse silicon carbide materials can already be supplied in large quantities and cannot be regarded as a high-tech product. The application of nano-scale silicon carbide powder with extremely high technical content is unlikely to form economies of scale in a short time.
1.As an abrasive, it can be used to make abrasive tools, such as grinding wheels, oilstones, grinding heads, sand tiles, etc.
2.As a metallurgical deoxidizer and high temperature resistant material.
3. High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers.
Main application: used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.
Used in semiconductors, lightning rods, circuit components, high temperature applications, ultraviolet light detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic films, cutting tools, heating elements, nuclear fuels , Jewelry, steel, protective gear, catalyst carrier and other fields.
