The production of high-quality black silicon carbide (Black SiC) involves several critical stages designed to optimize its physical and chemical properties for demanding industrial applications. Understanding these stages helps B2B buyers assess supplier capabilities and product suitability for specific use cases.
Manufacturing begins with sourcing high-purity raw materials, typically quartz sand and petroleum coke. These are carefully selected to minimize impurities, which directly affect the performance of the final product. The raw materials undergo crushing and grinding to achieve the desired particle size distribution before being blended in precise proportions.
The core manufacturing technique is carbothermal reduction. The prepared raw mix is heated to extremely high temperatures (around 2200°C) in an electric resistance furnace under controlled atmospheric conditions. This process converts silica and carbon into silicon carbide crystals. The furnace environment and temperature profile are closely monitored to ensure consistent crystal growth and minimize defects.
After the carbothermal reaction, the resulting silicon carbide lumps are cooled and then crushed to different particle sizes depending on the intended application — macro grit, micro grit, or powder. Precision classification systems separate particles by size and shape to meet stringent specifications, which is crucial for abrasive and electronic-grade Black SiC.
Finishing includes washing to remove residual impurities and surface treatments to enhance product stability and performance. For certain applications, Black SiC may be coated or chemically treated to improve bonding with resins or metals in composites. Packaging is also tailored to preserve product integrity during transport and storage.
