High Purity Silicon Carbide Powder
High-purity and ultra-fine ground silicon carbide fine powder products have high purity (the SiC content can generally reach 99.1%); high hardness (Mohs hardness between 3200-3400kg / mm2); concentrated particle size distribution (particle size standards are controlled by factory controls higher than Japanese JIS standards) Standard); high cleanliness, no attachments; good hydrophilicity, etc.
High-purity ultra-fine ground silicon carbide
Guangya high-purity ultra-fine grinding silicon carbide powder is made by using high-quality quartz sand and petroleum coke in a resistance furnace. The silicon carbide block obtained is crushed, washed with acid and alkali, magnetically separated and sieved, or water-selected to make ultra-fine Fine-grained products above 1000. Divided into black silicon carbide powder and green silicon carbide powder are two commonly used basic varieties are α-SiC.
Black silicon carbide fine powder is made of quartz sand, petroleum coke and high-quality silica through high-temperature smelting in a resistance furnace. Black silicon carbide contains about 98.5% of SiC. Its high toughness, brittleness and sharpness are mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron, and metals.
Green silicon carbide micropowder is made of petroleum coke and high-quality silica as the main raw materials, added table salt as an additive, and green crystals are formed by high temperature smelting in a resistance furnace. Green silicon carbide contains more than 99% SiC and has good self-sharpness. Most of them are used for hard processing. Alloys, titanium alloys, and optical glass are also used for honing cylinder liners and precision grinding of high-speed steel tools.
High-purity ultra-fine grinding silicon carbide fine powder
(1) As an abrasive, it can be used as abrasive tools, such as grinding wheels, whetstones, grinding heads, sand tiles, etc.
(2) As a metallurgical deoxidizer and high temperature resistant material.
(3) Single crystal with high purity, which can be used in the manufacture of semiconductors and silicon carbide fibers.
