Low price of silicon carbide powder 98% purity black silicon carbide
Silicon carbide (SiC) is made from quartz sand and petroleum coke or coal tar, wood chips and other raw materials by smelting in high temperature electric resistance furnace . In the high technology non-oxide refractory raw materials , such as C, N, B ,ilicon carbide is the most widely used and one of the most economic material. It can be called corundum or refractory sand.
It is brittle and sharp has electrical and heat conductivity in some degree.The abrasives made of it are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
CHARACTERISTICS
1.small thermal expansion
2.high thermal conductivity
3.not easy to have thermal stress
4.good thermal shock resistance
5.corrosion resistance
6.extreme cold or heat
7.high temperature creep resistant
ability
Applications for black silicon carbide
1. as an abrasive, it can be used as a grinding tool, such
as grinding wheel,oilstone,grinding head, sand tile,
etc.
2. As a metallurgical deoxidizer andexotic material.
3. High-purity single crystal, which can be used for
manufacturing semiconductors and manufacturingsilicon
carbide fiber.
4.It can be used as deoxidizer for steelmaking and modifier
for cast iron structure, and as raw material for
manufacturing silicon tetrachloride.
5.It can be used as high temperature indirect heating
material.
6. Anti-wear lubricants, structural coatings, functional
coatings, protective coatings, absorbing materials, stealth
materials, etc. in the industrial field
7. Glass polishing, rubber tires and other rubber products,
high-performance brake pads, product anti-wear lubrication,
high-hardness wear-resistant powder coatings;
8. High-performance structural ceramics (such as rocket
nozzles, nuclear industry, etc.), which can be used as
ceramic knives, cutting tools, measuring tools, molds;
special-purpose structural ceramics, functional ceramics,
composite ceramics, engineering ceramics;
9. Protective armor for tanks and armored vehicles;
10. Igniter; electric heating element for electrical
industry, far infrared generator.
