Green vs. Black Silicon Carbide: A Deep Dive into Production, Superior Properties, and Broad Applications

1. Production Process:

Black Silicon Carbide is produced not only from a mix of quartz sand, petroleum coke, and high-quality silicon stone but also through high-temperature smelting in an electric resistance furnace, ensuring its physicochemical stability.

In contrast, Green Silicon Carbide employs petroleum coke and ultra-pure silicon stone as raw materials, introducing table salt as a flux. This ensures higher crystal purity during the electric resistance furnace smelting.

2. Physicochemical Characteristics:

Black Silicon Carbide offers not just moderate hardness but also exceptional mechanical strength, making it a prime choice for numerous applications.

Green Silicon Carbide, on the other hand, due to its high crystal purity, surpasses many materials in hardness, boasting top-notch mechanical strength and durability.

3. Industry Applications:

In the grinding industry, whether it’s alloy, ceramics, or jade, black silicon carbide is indispensable. Green silicon carbide, due to its unique properties, is used for grinding hard alloys and optical glass.

Within the silicon carbide ceramics industry, black silicon carbide finds applications ranging from foam ceramics, pump bodies to granular particle capture filters. The outstanding performance of green silicon carbide has seen it used extensively in the production of bulletproof ceramics and reaction-sintered products.

In the abrasive tools industry, black silicon carbide’s role is undeniable, especially in coated abrasive tools. Green silicon carbide, given its unique advantages, has become the material of choice for various abrasive tools.

As technology continues to advance and industries evolve, we believe that the types and applications of silicon carbide will see even greater expansion. This article aims to provide a comprehensive understanding of these two materials, aiding experts in harnessing their unique strengths.
