Product Description
Silicon Carbide For Sale
Silicon carbide(silicon carbide block), also known as emery or refractory sand, has a chemical formula of SiC and is a very widely used inorganic substance. There are two types of silicon carbide obtained by industrial production, namely black silicon carbide and green silicon carbide.
Black Silicon Carbide
Black silicon carbide is produced by the reduction reaction of quartz sand and coke powder in a high-temperature environment. Its Mohs hardness is between 9.2-9.5, and its microhardness is 3300Kg/Cm3.

Black Silicon Carbide
Black silicon carbide is produced by the reduction reaction of quartz sand and coke powder in a high-temperature environment. Its Mohs hardness is between 9.2-9.5, and its microhardness is 3300Kg/Cm3.
Material characteristics: The content of SiC in black silicon carbide is more than 95%, and its strength and toughness are greater than that of green silicon carbide, but its hardness is lower. Most of it is used to process materials with low tensile strength,such as ground cast iron, non-metallic materials, glass, ceramics, and stone. , Refractory materials and non-ferrous metals.
Material advantages: The hardness of black silicon carbide is between corundum and diamond. It has high mechanical strength,stable chemical properties, high thermal conductivity, low thermal expansion coefficient, good wear resistance, and certainelectrical and thermal conductivity.

100#-180# | 98 | 0.3 | 0.8 |
220#-240# | 97 | 0.3 | 1.2 |
Green Silicon Carbide
Green silicon carbide is a non-metallic mineral produced by the reaction of quartz sand, petroleum coke, and sodium chloride under high-temperature conditions above 2000°C. The form of green silicon carbide is a green translucent crystal.
Material characteristics: The microhardness of green silicon carbide is between 3280-3400 kg/cm3, and it is mainly used for grinding hard gold-containing tools. Green silicon carbide can be used for consolidation and coating abrasive tools, free grinding, and polishing, etc. It is suitable for processing cast iron, cemented carbide, titanium alloy, high-speed steel, etc.
Material advantages: Green silicon carbide has the characteristics of high purity, high hardness, small expansion coefficient,brittleness, and good thermal conductivity.

Production Process
Silicon Carbide Production Process
Since the content of silicon carbide in nature is very small, the silicon carbide block is mostly industrially manufactured. The production of silicon carbide blocks uses quartz and petroleum coke as raw materials, and the raw materials are ground into a suitable particle size through processes such as grinding. After grinding the raw materials according to a certain ratio, they are put into an electric furnace for high-temperature heating to make a silicon carbide block. In order to adjust the gas permeability of the charge, it is necessary to add an appropriate amount of wood chips during the smelting process, and an appropriate amount of salt is also required to prepare green silicon carbide.
The silicon carbide production equipment uses a dedicated silicon carbide electric furnace. The power of the electric furnace is turned on and the silicon carbide production is started. When the center of the furnace temperature reaches 2500℃~2700℃ and the charge temperature reaches 1450℃, the raw materials react to produce silicon carbide and release CO. When the charge temperature is ≥2600℃, the already produced SiC will be partially decomposed, but the decomposed Si will form SiC with the C in the charge.
