What is Silicon Carbide?
Silicon carbide (SiC) is a highly abrasive and wear-resistant blasting material known for its extreme hardness and sharp edges. It is produced in an electric resistance furnace at high temperatures and is recognized for its excellent abrasiveness and resistance to thermal shock. Silicon carbide is ideal for surface treatment of hard materials and is widely used in industries for demanding blasting applications
