Specifications

Description

Black Silicon carbide powder is acid pickled an water separated powder with an extreme hardness after producing at high temperature in an electric resistance type furnace with quarts sand and petroleum coke.

 

Black Silicon Carbide is produced by a process involving the electrochemical reaction of silica(SiO2) – in the form of quartz  mixed with Carbon(C) in the form of raw petroleum coke. The stoichiometric mixture is reacted in an electrical resistance furnace at a temperature up to 2500˚C to yield high quality crystals. The process is large furnace technology with a graphite electrode in the furnace center.  The large crystals are then segregated, crushed, cleaned of magnetic impurities in high intensity magnetic separators and classified into narrow size fractions to suit the end use. Dedicated lines produce products for different applications. The micro powder form silicon carbide from HAIXU Abrasives is with good size distribution, high purity, and low impurities.

 

Properties:

High hardness, retaining hardness and strength at high temperature.

High wear resistance.

Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.

Good ability to withstand the strongest alkalis and acids.

 

Applications:

Ceramic products like silicon carbide ceramic seal.

Lapping, polishing.

Insulation

Wire sawing

Metallurgical:85% SiC is good deoxidant to increase speed of steel making.

Cutting material such as stone, silicon wafers.

Raw material of Knife Grinder, Whetstone, oilstone, grinding stone, honing, sharpening sticks, etc.

Material of Polishing wax, polishing fluid, grinding powder, grinding fluid and so on

Wear-resisting floor and non-slip coating such as additive for epoxy resin floors.

Brake linings

Semiconductor industry.
