Характеристики









The production method of green silicon carbide powder is basically the same as that of black silicon carbide, but the requirements for raw materials are different. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw materials, and salt is added as an additive. It is smelted by resistance furnace at high temperature. The crystallized crystal has high purity and high hardness, and its hardness is between corundum and diamond.

Application


Application
1.Abrasive tools.
Green silicon carbide is used to manufacture abrasive abrasives such as grinding wheels, sandpaper, sand belts,whetstones, grinding blocks, grinding heads and grinding pastes. These products play a key role in the processing of metal and non-metal materials, such as the cutting and finishing of wafers in the semiconductor, solar photovoltaic industry,piezoelectric crystal industry and other fields.
2.Functional ceramics.
Green silicon carbide because of its high thermal conductivity, high thermal strength and good heat resistance, is used to manufacture sheet kiln furniture, this material has a wide range of applications in the ceramic industry,such as in the baking and sintering process of ceramic glaze as an ideal indirect material.
3.Metallurgical dressing.
Green silicon carbide because of its high hardness and wear resistance, is used as a wear-resistant pipe,bucket lining and other materials, its wear resistance even exceeds cast iron and rubber, so it is also used in aviation runwayand other occasions.
4.Refractory and corrosion-resistant materials.
Green silicon carbide because of its high temperature and corrosion resistance, is usde in the production of high temperature silicon carbon rod heating element, far infrared source substrate and so on.
