The price of petroleum coke, the main raw material of silicon carbide, rose by about 140 USD per Ton after Chinese New Year. That directly led to an increase in the cost of black silicon carbide and green silicon carbide. Many silicon carbide manufacturers in China have raised prices.

Silicon carbon rods are commonly used high-temperature electric heating components. They are usually made of silicon carbide and other materials by blanking and firing. Black silicon carbide sand is its main raw material.

SiC porous ceramics has excellent advantage than other ceramics. Such as high strength, excellent corrosion resistance, high temperature resistance, high thermal conductivity, low thermal expansion coefficient, good thermal shock resistance. So it is an ideal vacuum chuck ceramic in semiconductor industry for bonding, cutting,tape installation, polishing,etc. Silicon carbide fine powder is just the raw material for SiC porous ceramic vacuum chuck.

Black silicon carbide 120mesh is suitable for the production of SiC ceramic seal rings.  98.5% SiC grains unique performance characteristics, including high hardness wear resistance, corrosion resistance, and excellent high temperature performance. There are several advantages of Black SiC 120mesh for this application

Black silicon carbide sand is an artificial abrasive grit for coated abrasives. Sanding fiber disc with SiC abrasive is suitble for stainless steel deburring, alloy and wood surface cleaning,etc. But not all black silicon carbide is qualified for this application. High cleanness and low conductivity of Black silicon carbide P24-P180 is very important for electrostatic sand-planting process.

Green silicon carbide is an excellent abrasive powder in industry. Usually used for grinding titanium alloys, quartz glass, and stone. Green silicon carbide also plays an important role in nail tools and body care. Green SiC powder F60 F100 F150 are suitable for sand caps making.
