Sintered Ceramic Powder β-Sic Silicon Carbide Powder
Spec: 50nm, 100-200nm, 1-2um or 5-6um and so on, particle size is adjustable. 99% purity, green powder.
Applicaiton and features for the silicon carbide powder:
β-SiC powder has a high chemical stability, high hardness, high fever conductivity, low thermal expansion coefficient, wide band gap, high electron drift velocity,high electron mobility, a special resistance temperature characteristics, and therefore has anti-wear, high temperature, thermal shock resistance, corrosion resistance, radiation resistance, good semi-conductive characteristics and excellent performance, are widely used in electronics,information, precision processing technology, military, aerospace, high-level resistance fire materials, special ceramics, advanced materials and grinding and enhancements materials and other fields. Its scope of application is divided into the following categories:
β-Sic in advanced structural ceramics, functional ceramics and advanced refractories market has a very broad application prospects. Common SiC during sintering requires 2300 ℃, 2400 ℃, 2500 ℃, additive remains even after 2100 ℃ before crystallization, and β-Sic at 1800 ℃ to crystallize, and the conversion process in the crystalline form of β-Sic , which will change the volume of the ceramic sintered compact performance play a good role, thereby increasing the overall performance of silicon carbide ceramic toughness and strength. Add the β-Sic boron carbide ceramic product can be improved in the toughness of the product while lowering the sintering temperature, so that a substantial increase in the performance of boron carbide ceramic.
