At Henan Sanhui, we specialize in two primary types of silicon carbide: Black Silicon Carbide and Green Silicon Carbide. These materials are renowned for their exceptional hardness, thermal properties, and versatility, making them ideal for demanding industrial applications. Black Silicon Carbide is produced from petroleum coke and silica sand, while Green Silicon Carbide is derived from high-purity silica and coke, resulting in a product with fewer impurities.

The chemical composition of Black Silicon Carbide typically includes silicon carbide (SiC) at 98-99.5% purity, with trace elements like iron and carbon. Green Silicon Carbide boasts even higher purity, often exceeding 99.9% SiC, which enhances its performance in precision applications. Both variants exhibit outstanding hardness—ranking 9.0-9.5 on the Mohs scale—making them harder than corundum and suitable for aggressive wear scenarios.
In abrasive blasting, Black Silicon Carbide shines due to its angular grain structure and high fracture toughness, allowing for efficient surface preparation on metals and ceramics. It removes rust, paint, and contaminants quickly, reducing processing time by up to 30% compared to traditional abrasives. Green Silicon Carbide, with its finer grains, offers superior edge definition, making it perfect for delicate blasting tasks in aerospace and automotive industries.
Key advantages include enhanced cutting speed and minimal heat generation, which prevents warping of workpieces. For B2B clients, this translates to cost savings and improved productivity, as our silicon carbides maintain their sharpness longer than alternatives like aluminum oxide.
Lapping applications benefit from the consistent particle size and thermal stability of our silicon carbides. Black Silicon Carbide is widely used for grinding and lapping hard materials like steel and glass, achieving mirror-like finishes with minimal subsurface damage. Its thermal conductivity—around 120 W/mK—helps dissipate heat during high-speed operations, extending tool life.
Green Silicon Carbide excels in ultra-precision lapping for semiconductors and optics, where its low thermal expansion coefficient (about 4.0 x 10^-6/K) ensures dimensional accuracy. These properties make our products essential for electronics manufacturers, providing a competitive advantage in producing high-performance components.
In refractory applications, both Black and Green Silicon Carbide offer excellent resistance to thermal shock and chemical corrosion, ideal for lining furnaces and kilns. Black Silicon Carbide's high melting point (over 2,700°C) makes it suitable for extreme environments in steel production and cement manufacturing. It improves the durability of refractory bricks, reducing maintenance downtime.
Green Silicon Carbide, with its superior purity, is preferred for advanced refractories in the chemical industry, where it withstands acidic conditions without degradation. Typical use cases include kiln furniture, crucibles, and thermal insulation, enhancing energy efficiency and longevity in high-temperature processes.
The thermal properties of silicon carbide are a major reason for its popularity. Both variants have low thermal expansion and high thermal conductivity, ensuring stability under rapid temperature changes. For instance, in abrasive blasting, this prevents thermal fatigue, while in refractories, it maintains structural integrity at elevated temperatures.
Hardness is another critical factor; Black Silicon Carbide's density (around 3.2 g/cm³) and fracture strength make it robust for heavy-duty tasks. Green Silicon Carbide, slightly less dense at 3.2 g/cm³, offers better friability for finer applications. These attributes, combined with our quality control, ensure our products meet or exceed industry standards for B2B use.
What is the difference between Black and Green Silicon Carbide? Black Silicon Carbide is more cost-effective and suited for general abrasive and refractory uses, while Green Silicon Carbide offers higher purity for precision applications like lapping and electronics.
