What is silicon carbide 88/90? In which fields is it used?
Introduction:
Silicon Carbide 88/90 (SiC 88/90) is a metallurgical-grade silicon carbide widely used in steelmaking, foundries, and refractory industries. Unlike high-purity SiC used in ceramics, this grade focuses on furnace reaction efficiency, cost effectiveness, and dual element contribution (Si + C). ZhenAn supplies SiC 88/90 in multiple particle sizes, ensuring stable performance in high-temperature applications.
Key Specifications of SiC 88/90
SiC content: 88–90%
Fixed carbon: 2–6%
SiO₂ and other oxides: 3–6%
Forms: Lumps, granules, powder
Moisture: Low for furnace feeding
Note: Size distribution affects furnace dissolution and reaction rate. ZhenAn provides screened particle sizes for EAF, induction furnace, ladle, and cupola feeding systems.
