SiC-90 black silicon carbide with a purity level of approximately 90% is classified as a secondary grade material.
With an SiC content between 90% and 92%, it is typically used in metallurgical and refractory applications, rather than in abrasive processes, due to its lower purity level.
Thanks to its balanced composition and high thermal resistance, 90% purity black silicon carbide is widely used in various industrial processes - especially where abrasive properties are secondary to chemical and thermal performance. Key application areas include:
