Black/Green Various Sizes High Purity Silicon Carbide

    Silicon carbide is a synthetic raw materials produced by silica sand and coke (or anthracite), add salt and wood chips at 2000-2500℃ high temperature resistance furnace. 

    Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high temperatures. Silicon carbide’s varied properties make it an effective material in many different applications.

Black silicon carbide is very hard, sharp and brittle. Its grain edges are sharp and it is of a certain capacity of heat transmission. Black SiC is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials.

    Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. 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.

Green Silicon Carbide is extremely pure & extremely hard, coming in at a Knoop 2600. It is typically only used for high tech, critical applications due to its cost. Like black silicon carbide, it will splinter as it breaks down, making excellent for recycling. It is the media of choice for wire sawing and sintering. It also has a high thermal conductivity.

Properties:
1,Avoid the precipitation of carbide and diminish the white layer.
2,Increase the cutting and mechanical property.
3,Increase the flowability ,and stablity of melten iron, and avoid the segregation.
4,Decrease the sectional sensitivity.
5, reinforce the capacity of heterogeneous nucleation of graphite..
6, To ductile cast iron, Silicon Carbide is a strong deoxidizer which decrease the the amount of nodulizer and increase the nodularity.
7,Reduce the costs of molten iron by reducing the rusty scrap.
8,Reduce the the damage on the furnace wall and prolong its durability..
9,Powerful deoxidation on purifying the molten iron.

Usage:
1. Metallurgical deoxidizer.
2. High temperature resistant materials.
3. As abrasive, abrasive tools can be used to such as grinding wheels, whetstones,
