Product Description

Black Silicon Carbide

Black Silicon Carbide(SiC) is the product of silicon quartz sand and petroleum coke electro fused at high temperature in an electrical resistance furnace. The grains of Black Silicon Carbide are hexagonal crystals that are extremely hard, sharp, friable, and high strength(at 1000℃, SiC is 7.5 stronger than Al2O3), and have outstanding electrical and thermal conductivity and low thermal expansion.

Advantages of Black Silicon Carbide in Bonded Abrasives:

1. Exceptional hardness and wear resistance
Given the relative ratio of ordinary abrasives, under the same conditions, the blackened silica abrasive tools show longer service life and improved abrasive performance. Specially, when processing high-hardness materials, the black silica polishing grains do not easily harden, retaining the ability and advantageous cutting edge, ensuring processing efficiency and durability.
2. Different thermal characteristics and chemical characteristics
Black Silicon Carbide has good physical performance under high temperature environment, suitable for use in blackened silicone polishing tools under high speed, heavy load grinding conditions, not easy to change shape or crack when heated. At the same time, the black powdered silica acid has good resistance ability, and under the current wet environment or special coolant conditions, it does not react easily with biochemical reaction, and the polishing tool performance is guaranteed.
3. Features of special features
After theBlack Silicon Carbide crystal is broken, it has the ability to form a polygonal grain with a sharp edge, and has the cutting ability of abrasive material. The most important point is that black silica polishing grains have unique self-resistance during the use process - after polishing the abrasive grain tips, there is a new cutting edge that bursts under the action of force, and is non-pure. This characteristic has a longer effective service life and a reduced renewal rate.

Application

1. Bonded Abrasives: It is an ideal materials for Vitrified Grinding Wheels, Resin Grinding Wheels, Brake Pads/ Block, Frankfurt, Marble Polishing Stones, Oil Stones, Mounted Stones, Polishing Sticks.
2. Coated Abrasives: It is used to make coated abrasive products, such as sandpaper and are available in sheets, discs, rolls, belts, pads wheels and other forms.
3. Sandblasting / Polishing / Lapping: It is useful for grinding glass, removing mill scales and any other application where aggressive abrasives are required.
4. Refractories: furnace and incinerator linings, kiln furniture, fire bricks, refractory cement, electric heating elements, etc.
5. Anti Slip Pavement: Black Silicon Carbide can be used in the surface of out door pavement, which are heavily trafficked area that must provide traction or stand up to heavy wear, environmental stresses, weathering and slip resistance. Such as deck of the ship, highway speed bumps, airport runway.

6. Metallurgical: Steel plants use silicon carbide as an additive to molten metal to act as a source of carbide and silicon.

7. Wire Sawing: Precise silicon carbide powders are used in the cutting of silicon wafers. Silicon carbide is an excellent material for wire sawing silicon ingots into wafers for photovoltaic and semiconductor applications. 

8. Ceramic: High density and low porosity features make silicon carbide for high performance application, such as advanced or technical ceramic.
