Black silicon carbide is a superior material for abrasives. It is suitable for both bonded abrasive wheels and coated abrasive tools. Generally, F grit macro black silicon carbide is for bonded abrasives such as grinding disc and wheels. P grit macro black silicon carbide is for bonded abrasives such as waterproof sanding paper, sanding sheets, polishing wheels, etc. Bulk density is one of the key factors for black SiC grains. High density means more grains packed in the same shape as grinding wheels. That will make the abrasive wheel life longer.

A soft bulletproof vest can only protect against low-speed bullets. For high-speed bullets or some steel core bullets fired from rifles, it can get bulletproof by inserting hard shields at key positions based on soft bulletproof vests. At present, hard guard armor made from Silicon carbide composite ceramic plates can meet the requirements of proper weight, performance, and price.  Black silicon carbide grain and powder can be raw materials to produce bulletproof armor.
