Description
Black Silicon Carbide Powder #2000 is an ultra-fine silicon carbide micropowder manufactured from high-purity petroleum coke and silica sand through high-temperature electric resistance furnace smelting, followed by precision milling and advanced particle classification.
Featuring exceptional hardness, sharp microscopic particle morphology, and highly uniform particle size distribution, Black Silicon Carbide Powder #2000 provides extremely fine cutting performance while producing very smooth and refined surface finishes. Its ultra-fine particle size makes it particularly suitable for applications requiring minimal surface roughness, excellent dimensional accuracy, and superior polishing quality.
Compared with Black Silicon Carbide Powder #1000, #2000 offers a significantly finer particle distribution that further improves polishing efficiency, enhances surface smoothness, and reduces micro-scratches during finishing operations while maintaining reliable abrasive performance. It is widely used in ultra-precision polishing, lapping, optical glass processing, ceramic manufacturing, semiconductor materials processing, precision components, refractory products, and other advanced industrial applications.
With excellent wear resistance, thermal stability, and consistent product quality, Black Silicon Carbide Powder #2000 is an ideal abrasive material for manufacturers requiring ultra-fine micropowder solutions for mirror-like finishing and high-precision industrial processing.
