كربيد السيليكون الأخضر
كربيد السيليكون الأخضر (كذا) هو نقي للغاية, البديل جودة مميز من كربيد السيليكون, distinguished by its green color. Produced through the Acheson process, green SiC is obtained by heating a mixture of high-purity silica sand and petroleum coke in the presence of trace amounts of iron. This results in a material with exceptional hardness and a higher purity level compared to black SiC.
Owing to its superior hardness, green SiC is primarily utilized as an abrasive material for high-precision grinding and polishing applications in the automotive, aerospace, and electronics industries. It is also employed in the production of cutting tools, grinding wheels, and abrasive papers, where its pure composition ensures minimal contamination and smoother finishes.
In addition, green SiC has found use in advanced electronics and semiconductor devices, thanks to its excellent thermal and electrical properties. Its high purity makes it a preferred choice for manufacturing critical components in high-voltage power electronics, optoelectronics, and high-frequency devices. Green SiC also plays a role in the fabrication of wear-resistant and corrosion-resistant materials, as well as in the development of advanced ceramic components.
