Black SiC 90% Powder Overview for Industrial Applications
Black SiC 90% powder is a metallurgical-grade silicon carbide 90% material designed for high-temperature industrial processes. Manufactured from quartz sand and petroleum coke through electric resistance furnaces, it offers a stable combination of thermal resistance, chemical stability, and cost efficiency.
This grade is widely used by European steelmakers and foundries looking for a reliable silicon carbide supplier capable of delivering consistent quality for bulk operations.
Key Advantages of Silicon Carbide 90% Powder
High-Temperature Performance of Black Silicon Carbide Powder
Black silicon carbide maintains stability at temperatures exceeding 1600°C, making it suitable for electric arc furnaces (EAF), ladle furnaces, and other high-temperature systems.
Deoxidizer and Carburizer Function of SiC 90%
As a silicon carbide deoxidizer, SiC 90% effectively removes oxygen from molten steel. At the same time, it acts as a carburizer, improving carbon content and enhancing steel quality.
Cost-Effective Metallurgical Silicon Carbide Solution
Compared with higher-purity grades, industrial SiC 90% powder provides an optimal balance between performance and cost-ideal for large-volume procurement.
Wear-Resistant Black SiC Abrasive Material
With high hardness (Mohs 9+), black SiC is widely used in abrasive and grinding applications, ensuring long-lasting performance.
