1. Make tools with ceramic materialsIn machining of metal materials, machining is the most basic and reliable method of precision machining. In modern machining, ceramic tool materials play more and more important roles in high speed cutting and difficult cutting materials due to their excellent heat resistance, wear resistance and chemical stability. Ceramic tool material mainly includes alumina, silicon nitride and theron series. Other ceramic materials such as zirconia and titanium boride are also used as tool materials.2. Alumina seriesPure alumina ceramics contain more than Al 2 O 3 99%, with low strength, poor thermal shock resistance and fracture toughness. Carbide, nitride and boride materials have high strength and hardness and can be used as the reinforcing phase in Al 2 O 3 cera...

Zirconium dioxide (chemical formula: ZrO2) is the main oxide of zirconium, usually white odorless, odorless and tasteless crystal, difficult to dissolve in water, hydrochloric acid and dilute sulfuric acid. It usually contains a small amount of hafnium dioxide. The chemical properties are not active, and the properties of high melting point, high resistivity, high refractive index and low thermal expansion coefficient make it an important high temperature resistant material, ceramic insulation material and ceramic shader. It is also the main raw material of artificial drilling, and the energy ...

As is known to all, the main raw material of alumina ceramic sheet is alumina, which has certain unique advantages. It is known that alumina ceramic plate is a kind of material with high thermal conductivity and high insulation, with a thermal conductivity of 25W/m.k and a pressure resistance of 13KV. (the thermal conductivity of silicon film is 0.6w /m.k and a pressure resistance of 2KV), it has become the best choice for high-power equipment due to its excellent performance and high cost performance.Where is the application of alumina ceramic sheet? Mingrui ceramics are introduced in detail:...
