black silicon carbide abrasive is the hardest blasting media available. High-quality silicon carbide media is manufactured to a blocky grain shape that splinters. The resulting silicon carbide abrasives have sharp edges for blasting. Silicon carbide has a very fast cutting speed and can be recycled and reused many more times than sand. The hardness of silicon carbide allows for much shorter blast times relative to softer blast media.

2.Chemical & Physical Properties

1. Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.

2. Good hardness, longer life.

3. Chemical washed and water washed, good cleanness.

4. Special treated products get higher purity, better toughness, and better grinding effect.
