Which Industries Use Silicon Carbide 88/90 Grade Most?
Silicon Carbide 88/90 is one of the most widely used grades of metallurgical silicon carbide in high-temperature industrial processes. Due to its balanced SiC content, reduction efficiency, and cost effectiveness, Silicon Carbide 88/90 is heavily used in steelmaking, foundry melting, and refractory production.
ZhenAn supplies stable-quality Silicon Carbide 88/90 for global metallurgical buyers, steel plants, and foundries that require consistent reaction performance and economical furnace additives.
This guide explains exactly which industries use Silicon Carbide 88/90 the most and why this grade is often preferred over higher-purity alternatives.
What Is Silicon Carbide 88/90 Grade?
Silicon Carbide 88/90 (SiC 88/90) is a metallurgical-grade silicon carbide material typically used as a deoxidizer, reducer, and silicon-carbon additive in furnace operations.
Typical specification range:
SiC content: 88–90%
Fixed carbon: process dependent
SiO₂: controlled range
Form: lumps, granules, powder
Application class: metallurgical silicon carbide
Compared with abrasive or ceramic grades, Silicon Carbide 88/90 is optimized for reaction efficiency and furnace economics, not ultra-high purity.
ZhenAn produces Silicon Carbide 88/90 with controlled particle sizing and batch stability suitable for industrial charging systems.

FAQ - Silicon Carbide 88/90
Is Silicon Carbide 88/90 good for steel deoxidation?
Yes. Silicon Carbide 88/90 is widely used as a composite deoxidizer and reducer in EAF and induction furnace steelmaking.
Can SiC 88/90 replace ferrosilicon?
It can partially replace ferrosilicon in many steelmaking and foundry processes to reduce alloy cost.
Is Silicon Carbide 88/90 used in aluminum production?
No. Aluminum metallurgy normally uses silicon metal rather than metallurgical silicon carbide.
Does higher SiC percentage always mean better performance?
Not always. Correct grade selection depends on furnace process, reaction goal, and cost model.
