Tag : Silicon Nitride Ceramic

Sulfide powder refers to the chemical compounds powder with large families of inorganic and organic compounds, e.g. copper sulfide, Zinc sulfide, molybdenum disulfide, tungsten disulfide powders and so on. Sulfides and their similar compounds include a series of metals and semi-metallic elements combined with S, Se, Te, As, Sb, Bi minerals. Applications of Sulfide powder Sulfide powders are widely used in industrial field. Molybdenum disulfide is a catalyst in organic synthesis. Since sulfur-containing organic compounds such as thiophene poison the common hydrogenation catalyst, molybdenum disulfide can be used to catalyze the hydrogenation reaction of sulfur-containing organic substances. Cadmium sulfide can be used to make photo-voltaic cells. Lead sulfide is used to make infrared sensors. Zinc sulfide and cadmium sulfide are used to make phosphors, and high purity cadmium sulfide is a good semiconductor. Tetraphosphorus trisulfide is used to make matches and fireworks. Tetraphosphorus tetrasulfide is used in the manufacture of insecticides, lubricating oil additives and flotation agents. Sodium sulfide is widely used in the manufacture of sulphur dyes, production of organic drugs and pulp, etc. Calcium sulphide and strontium sulfide are used to make luminescent lacquers. Cie-Chinamaterial supplier provide high purity molybdenum sulfide, tungsten disulfide, cadmium sulfide,bismuth sulfide,stannic sulfide,zinc sulfide, etc. Payment Term: T/T, Western Union, Paypal, Credit Card etc. Shipment Term: By air, by sea, by express, as customers request.

Comprehensive comparison and engineering application analysis of alumina, zirconia, silicon carbide and silicon nitride ceramics aluminum nitride cost

Material Overview Advanced architectural porcelains, because of their distinct crystal framework and chemical bond characteristics, reveal efficiency advantages that metals and polymer products can not match in extreme settings. Alumina (Al ₂ O FIVE), zirconium oxide (ZrO ₂), silicon carbide (SiC) and silicon nitride (Si two N ₄) are the four significant mainstream engineering ceramics, …

Application of Silicon Nitride Ceramics in Refractory Industry

Silicon nitride High strength especially when hot-pressed silica nitride. This is the hardest material in the world. It can withstand high temperatures without melting and maintains its strength up to 1200degC. It won’t melt in heat and it will not decay until 1900degC. It is extremely resistant to chemical corrosion. It is resistant to almost …
