Black Silicon Carbide FAQs

What is black silicon carbide and how is it different from green silicon carbide?

Black silicon carbide is a sharp, highly durable abrasive material made from quartz sand and petroleum coke at high temperatures. Compared to green SiC, it has slightly lower purity but higher toughness, making it ideal for grinding metals and heavy-duty blasting.

What industries and applications is black SiC best suited for?

Black silicon carbide is widely used in:
Grinding wheels & cutting discs (especially for cast iron and non-ferrous metals)
Pressure sandblasting of steel surfaces
Ceramic and refractory materials
Anti-slip flooring and coated abrasives

What grit sizes do you offer?

We offer a full range from F12 to F1200 (FEPA standard), as well as P-grits, JIS, and micro powders, to meet various surface finish and particle size needs.

Can I get a custom grit size or bulk density specification?

Yes. We support customization in particle size distribution, bulk density, and shape (blocky vs. sharp). Just share your technical requirements or usage scenario.

How pure is your black silicon carbide?

Our black SiC typically contains 98.5% SiC minimum. It is processed through air washing and magnetic separation to ensure minimal free carbon, iron, or other impurities.

Do you provide samples for testing?

Yes, we offer free samples for quality evaluation and lab testing. Contact us with your shipping details and technical needs.

What packaging options are available?

Standard 25kg bags or 1MT jumbo bags. OEM packaging and palletized shipments available upon request.

Where is your factory located, and do you support global shipping?

We are based in China with 30+ years of experience in SiC production. We ship globally with full logistics support and can assist with customs documentation and delivery coordination.
