Black Silicon Carbide 88–90% Supplier | Bulk Price | For Steel & Foundry
What is Black Silicon Carbide 88–90%?
Black Silicon Carbide (B-SiC) 88–90% is a metallurgical-grade silicon carbide material that combines high silicon content with carbon, supplied in various particle sizes suitable for steelmaking and foundry use. Its dark color indicates high purity and dense crystalline structure, which contributes to stable chemical performance in high-temperature processes.
Unlike green or other types of SiC, black SiC is particularly suitable for steel deoxidation, carbon adjustment, and foundry applications where both reactivity and stability are required. The 88–90% purity ensures reliable performance, while particle size options-from fine powders to larger lumps-allow customization for specific furnace or casting processes.
Why Use Black Silicon Carbide 88–90% in Steel & Foundry?
In steelmaking, controlling oxygen and carbon levels is crucial for producing high-quality steel. Black SiC 88–90% acts as a dual-function deoxidizer and carbon source, efficiently reducing oxygen content while contributing carbon where needed. Its stable lump or powder form ensures predictable melting and chemical reactions in furnaces, minimizing oxidation loss and improving silicon absorption.
For foundries, black SiC improves slag fluidity, reduces inclusions, and stabilizes molten metal during casting. Its high purity and dense structure allow for more consistent reactions, which reduces defects and scrap rates. Compared with conventional ferrosilicon, black SiC 88–90% often achieves higher efficiency with lower overall material consumption, making it a cost-effective choice for both steel and casting operations.
Applications
Black Silicon Carbide 88–90% is widely used in:
Steelmaking: Electric Arc Furnace (EAF), Converter, Secondary Refining
Foundry: Iron and steel casting, high-temperature furnaces
Situations requiring rapid deoxidation, precise carbon adjustment, and defect reduction
Large-scale operations where cost control and process stability are critical
