Production of Silicon carbide large particle powder:

In the production of silicon carbide, a mixture of carbon material (usually petroleum coke) and silica or quartz sand undergoes a high-temperature chemical reaction in an electric furnace to form silicon carbide. The resulting coarse material is further processed by crushing and grinding to obtain silicon carbide coarse powder of the correct shape and size. These Silicon carbide coarse powders are either washed with water or chemically treated to achieve higher material purity.

‌Advantages of Silicon Carbide Coarse Powder‌

Silicon carbide large particle powder is a versatile material prized for its unique combination of physical and chemical properties, making it superior to traditional alternatives in demanding applications.

‌Exceptional Hardness & Wear Resistance‌: With a Mohs hardness of 9.5, silicon carbide coarse powder outperforms most abrasives like aluminum oxide or quartz. This ensures prolonged durability in grinding, cutting, and surface preparation tasks, reducing tool replacement frequency and operational downtime.

‌High Thermal Stability‌: silicon carbide retains strength at temperatures exceeding 1600°C, far surpassing metals and ceramics. This makes it ideal for refractory linings, kiln components, and metallurgical processes, where thermal shock resistance minimizes structural failures.

‌Chemical Inertness‌: Resistant to acids, alkalis, and oxidation, silicon carbide maintains integrity in corrosive environments. This property is critical in chemical processing equipment, semiconductor manufacturing, and wastewater treatment systems.

‌Energy Efficiency‌: Its high thermal conductivity (120 W/m·K) enables rapid heat dissipation, improving energy efficiency in high-temperature industrial furnaces and electronic devices.

‌Lightweight & Eco-Friendly‌: Silicon carbide's low density reduces material consumption in composite manufacturing, while its longevity supports sustainable practices by lowering waste generation.

From abrasives to green energy technologies, Silicon carbide large particle powder delivers unmatched performance, cost savings, and environmental benefits, cementing its status as a cornerstone of modern industrial innovation.
