Our premium Silicon Carbide abrasives deliver exceptional performance across numerous high-precision industries:
Our engineering team can help determine the optimal Silicon Carbide specification for your specific industrial application and process requirements.
Challenge: A leading semiconductor manufacturer was experiencing inconsistent surface finish quality during silicon wafer production, resulting in 8% rejection rates and production delays.
Solution: Implementation of our F1000 Green Silicon Carbide in their precision lapping process, coupled with our proprietary particle size distribution control.
Results:
The primary difference lies in purity levels and performance characteristics. Green Silicon Carbide (GC) has a higher purity level (99.5%+) compared to Black Silicon Carbide (BC) at 98.5%. This higher purity gives Green SiC enhanced cutting properties, making it ideal for precision applications with hard materials like tungsten carbide, ceramics, and advanced composites. Black SiC is more economical and suitable for general-purpose grinding of ferrous metals, ceramics, and stone materials. The color difference results from the raw materials and manufacturing processes used.
For optimal performance and longevity of Silicon Carbide abrasives, store in a clean, dry environment with controlled humidity (ideally below 65% RH). Keep containers tightly sealed to prevent moisture absorption and contamination. Store powders and microgrit products in their original packaging or airtight containers. For bonded abrasives, store flat or as recommended to prevent warping or stress. Avoid temperature extremes or fluctuations, and implement inventory rotation (FIFO) to ensure product freshness. These precautions will help maintain the cutting effectiveness and prevent degradation of your Silicon Carbide abrasives.
Yes, Silicon Carbide performs exceptionally well in wet grinding operations and is often preferred for such applications. Its chemical stability makes it resistant to common coolants and lubricants used in industrial processes. Wet grinding with Silicon Carbide offers several advantages: improved thermal management, reduced airborne dust, better surface finish, and enhanced cutting efficiency. Our Silicon Carbide products are specifically formulated to maintain their integrity and performance in wet environments, making them ideal for precision wet grinding operations in semiconductor, optical, and ceramic manufacturing.
