SiC black carborundum powder F500
SiC black carborundum powder F500 is an extremely hard powder for both abrasion and thermal resistance applications. After chemical and water washing treatment, the SiC powder is pure enough to scatter quickly. With a narrow particle size range, it can meet the polishing work requirement. In the meantime, SiC black powder is suitable for thermal & heat insulation usages such as paint additives and SiC sintered ceramics. SiC black F500 is a very fine powder with a mean particle size of 10-12 microns.

FAQ：
Q: Are you a manufacturer?
A: We are a supplier of silicon carbide powder with more than 20 years of production experience. We began to produce silicon carbide powder since 1999.
Q: What grade of silicon carbide do you have?
A: We have several grades of silicon carbide powder including refractory grade, abrasive grade,etc.
Q: How will you check silicon carbide quality before delivery?
A: We will check the chemical composition and cleanness of the carborundum grain and powder. And inspect the gradation, bulk density of SiC grain and powder.
Q: Do you support third-party quality inspection?
A: Yes, we are open to getting a third-party quality test before delivery.
Q: Is the silicon carbide you supply reclaimed material?
