Black silicon carbide (SiC) is a cornerstone material in the abrasives and refractory industries, celebrated for its remarkable hardness, thermal conductivity, and chemical stability. As the global demand for high-performance abrasives, ceramics, and refractory products continues to rise, China has firmly established itself as the world's leading producer and exporter of black silicon carbide. This article provides a comprehensive overview of the top 10 black silicon carbide manufacturers in China, with Dragon Abrasives Group Limited taking the lead position. We will explore the history, capabilities, and strengths of each manufacturer, as well as the key qualities that make Chinese black silicon carbide so sought after worldwide.
Black silicon carbide is a synthetic crystalline compound produced by heating silica sand and petroleum coke in an electric resistance furnace at temperatures above 2000°C. The process results in a hard, sharp, and brittle material with a Mohs hardness of 9.5, making it ideal for a wide range of industrial applications. Black silicon carbide is used in grinding, cutting, lapping, polishing, and as a refractory material due to its outstanding physical and chemical properties.
- High Hardness: Mohs 9.5, second only to diamond and boron carbide.
- Thermal Conductivity: Excellent heat dissipation, suitable for high-temperature applications.
- Chemical Stability: Resistant to acids, alkalis, and oxidation.
- Electrical Conductivity: Useful in electronic and semiconductor industries.
The manufacturing process of black silicon carbide involves several critical stages:
1. Raw Material Preparation: High-quality silica sand and petroleum coke are selected and mixed.
2. Mixing: The materials are blended to achieve the desired chemical composition.
3. Crushing and Grinding: The mixture is ground into a fine powder for uniformity.
4. Carbonization: The powder is heated in an electric resistance furnace at 2000–2500°C, forming solid SiC crystals.
5. Crushing and Sizing: The solid mass is crushed and classified into various grit sizes for different applications.
This controlled process ensures that the final product meets stringent quality standards for industrial use.
Black silicon carbide's unique combination of hardness, thermal stability, and chemical resistance makes it a versatile material for many industries:
- Abrasives: Used in grinding wheels, cutting discs, sandpaper, lapping, and polishing media.
- Refractories: Essential for high-temperature kiln linings, foundry crucibles, and furnace parts.
- Ceramics: Added to wear-resistant and high-strength ceramic products.
- Electronics: Serves as a substrate material for semiconductors and power electronics.
- Surface Treatment: Used in sandblasting and cleaning of metal surfaces.
