Black Silicon Carbide for Refractory Applications
Product Overview
SiCera’s Black Silicon Carbide grains are engineered for high-performance refractory applications requiring exceptional hardness, high-temperature strength, and chemical resistance. Produced under tightly controlled conditions, our SiC delivers consistent performance in demanding thermal and corrosive environments.
SiCera provides a flexible range of specifications (purity, grain size, and density) to match diverse customer requirements—from standard refractory use to advanced high-density applications.
Our Advantage
High Purity (up to ≥98.5% SiC): Ensures superior thermal and mechanical stability.
Low Magnetic Iron Content: Optional low-iron grades available for sensitive applications.
Thermal Stability: Reliable strength and corrosion resistance above 1,600 °C.
High Density & Hardness (Mohs 9.2–9.5): Superior wear and erosion resistance.
Tailored Grain Morphology: Cubic or sharp-edged grains to optimize packing, sintering, and thermal shock performance.
Applications
SiCera Black SiC is trusted across industries for:
Refractory Bricks & Castables: Enhances strength and thermal shock resistance.
Kiln Furniture & Saggers: Provides long service life under repeated heating cycles.
Crucibles for Metallurgy: Withstands aggressive molten metals and alloys.
Monolithic Refractories & Coatings: Improves erosion and corrosion resistance in furnaces.
Foundry & Iron/Steel Industry: Used in troughs, ladles, and blast furnace linings.
