88%Sic 90%Sic98%Sic Silicon Carbide

Metallurgical-grade silicon carbide (SiC ≥98%) is engineered to optimize alloy performance in iron and steel production. With a controlled composition of 98.5-99.2% SiC, 0.3% max free carbon, and 0.5% max SiO₂, our material acts as a powerful deoxidizer and carburizing agent. The hexagonal alpha-phase crystal structure ensures rapid dissolution in molten metal, reducing slag formation by 25% compared to conventional additives. Available in granular forms (1-10mm) or briquettes (50mm x 50mm), our SiC enhances tensile strength in cast iron by 15-20% while lowering production costs through reduced energy consumption (estimated 8-12% savings per ton).

Our standard grades include: SiC 98%: ≤0.5% Fe₂O₃, bulk density 1.6-1.8g/cm³, ideal for ductile iron modification. SiC 99%: ≤0.3% Al₂O₃, tailored for high-purity steel smelting. All products comply with ISO 9286:2012 and ASTM C863 standards, with customizable particle size distributions (+/- 0.5mm tolerance).

Leveraging our annual production capacity, we guarantee batch-to-batch consistency through AI-controlled rotary kilns operating at 2,400°C. Our proprietary impurity removal process achieves 99.97% metallic impurity elimination, validated by third-party SGS reports. Just-in-time delivery is ensured via our dedicated rail network connecting to major Asian ports.
