High quality 99% sic black/green silicon carbide abrasive grain carborundum powder for lapping compound
Slicon Carbide Introduction
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.
Silicon Carbide Powder Feature
1) Silicon carbide (SiC) is also called moissanite, commonly known as carborundum. Made from quartz sand, petroleum coke (or coal), wood sawdust as raw material through the resistance furnace and high temperature melting.
2) Silicon carbide is very hard, Mohs hardness of 9.5, second only to the world's most hard diamond (10), has excellent thermal conductivity, is a semiconductor, high temperature resistant to oxidation.
3)In the C, N, B and other non-oxide refractory materials of high-tech, Silicon carbide is one of the most widely used and economical ones.
4) At present, China's industrial production is composed of silicon carbide black and silicon carbide green, which are hexagonal, the proportion is 3.20 ~ 3.25, the hardness is 2840 ~ 3320kg/mm2.
5) The black silicon carbide containing SiC about 95%, its toughness is higher than green silicon carbide, mostly used in materials processing with low tensile strength, such as glass, ceramics, stone, refractory material, cast iron and non-ferrous metals. The green silicon carbide containing SiC about 97% or above, good self-sharpenness, mostly used for processing hard alloy, titanium alloy and optical glass, also used for honing cylinder liners and grinding high-speed steel cutting tool. In addition, cubic silicon carbide, which is yellow green crystal got from a special process, used to make abrasive tools for superfinishing, can make the surface roughness from Ra32 ~ 0.16 micron to Ra0.04 ~ 0.02 micron.

Applications for 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.
