What is Green Silicon Carbide SiC
Green silicon carbide (SiC) is a form of silicon carbide that has a green color due to the addition of small amounts of chromium and/or iron to the crystal lattice. It has similar properties to black silicon carbide, including high hardness, good thermal conductivity, and excellent resistance to corrosion and abrasion.Green SiC is widely used in the production of abrasive materials, including grinding wheels, sandpaper, and cutting tools. It is also used in the production of refractory materials, ceramics, and semiconductors. In the electronics industry, green SiC is used as a substrate material for high-power electronic devices, such as high-voltage diodes and transistors.
Types of Green Silicon Carbide SiC
Crude green silicon carbide
This type of SiC is produced by melting a mixture of silica sand and petroleum coke in an electric furnace at a temperature of approximately 2,400°C. The material is then cooled and crushed to the desired grain size.
Refined green silicon carbide
This type of SiC is produced by further processing crude green silicon carbide using a series of steps that involve washing, acid leaching, and thermal treatment. The resulting product is a finer and more uniform grain size with improved purity and chemical composition. Refined green silicon carbide is typically used in higher-end applications such as advanced electronics, high-performance abrasives, and semiconductor devices.
Green silicon carbide is a synthetic abrasive composed of silicon carbide and additional materials such as iron, aluminum, and titanium. Its specific ingredients and quantities depend on the manufacturer, but typically it contains between 98-99% silicon carbide, with the remaining 1-2% consisting of various impurities and additives to enhance its grinding performance. The precise composition of the additives can vary based on the application and intended use of the abrasive material.
