Green Silicon Carbide Powder for Glass Polishing Key Properties for Glass Polishing High hardness (Mohs 9.2–9.5), harder than glass, enabling efficient material removal. Excellent self-sharpening – micro-fractures during polishing maintain sharp cutting edges. High chemical purity (typically ≥98% SiC) → no staining or contamination on glass surfaces. Good thermal conductivity → reduces heat buildup, minimizing
Black Silicon Carbide (Black SiC), with the chemical formula SiC, is a synthetic ceramic material made by fusing quartz sand and petroleum coke at ~2200 °C. It features Mohs hardness ~9.2, high temperature stability (melting point ~2700 °C), excellent thermal shock resistance, chemical inertness, and wear resistance. Cost-effective and tough, it is widely applied in refractories for high-temperature furnaces, iron and steel troughs, abrasives (grinding wheels, sandblasting), metallurgical additives, and wear-resistant coatings, differing from green SiC by its lower cost and broader industrial use.
Silicon carbide refractory is a high-performance refractory product made mainly from SiC (silicon carbide) as aggregate and powder, combined with binders (clay, oxide bond, nitride bond, etc.) and sintered at high temperature.
Black silicon carbide powder is a high-purity advanced ceramic material synthesized via Acheson process, featuring exceptional hardness, thermal stability, electrical conductivity, and chemical inertness. It is widely used as a functional filler, abrasive, and reinforcement in high-value industries.
Green silicon carbide (SiC) micropowder is widely recognized as an excellent precision polishing media for stone, glass, ceramics, and hard non-metallic materials.
The use of silicon carbide (SiC) for stone polishing is a classic and highly effective application. Why Silicon Carbide? Silicon carbide is an ideal abrasive for stone due to its unique combination of properties: Extreme Hardness: With a Mohs hardness of 9.5, it is significantly harder than almost all natural stones (granite ~6-7, marble ~3-5, quartzite ~7).
