What are the methods for removing iron from silicon carbide Physical iron removal method: The silicon carbide grain size sand produced by Zhengzhou Haixu Abrasives Co., Ltd. generally purchases a 8000-gauss roller magnetic separator, and adjusts the feeding speed and the size of the baffle plate according to the customer’s use and iron requirements to
What is the difference between silicon powder and silicon carbide powder? Silica fume is also called micro-silica fume, the scientific name is “silica fume”, also known as silica fume. It is collected and processed by a special collection device in the process of industrial electric furnace smelting industrial silicon and ferrosilicon at high temperature. .
The most important semiconductor material in the 5G era: silicon carbide Entering the 5G generation, most 5G products have the characteristics of high power, high voltage, and high temperature. Traditional silicon (Si) raw materials cannot meet the technological needs of the new generation because they cannot overcome the loss in high voltage and high frequency.
Why is silicon carbide green and black? Black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted by resistance furnace at high temperature. The raw materials used in the manufacture of green silicon carbide, such as black silicon carbide, are roughly the same, and
structure of silicon carbide Pure silicon carbide is a colorless and transparent crystal. Industrial silicon carbide is light yellow, green, blue or even black due to the type and content of impurities, and its transparency varies with its purity. The crystal structure of silicon carbide is divided into hexagonal or rhombohedral α-SiC and cubic β-SiC
Green silicon carbide powder has higher hardness and mechanical strength than corundum Green silicon carbide powder is green, with crystal structure, high hardness, strong cutting ability, stable chemical properties and good thermal conductivity. The microscopic shape is hexagonal crystals. The Mohs hardness of silicon carbide is 9.2, and the Vickers micro hardness is 3000-3300 kg/mm.
