Silicon carbide
Emery sand, also known as silicon carbide (SiC), is made of quartz sand, petroleum coke (or coal coke), wood chips (the production of green silicon carbide needs adding salt) and other raw materials through the resistance furnace high temperature smelting。

Purpose:
Silicon carbide is mainly used in functional ceramics, high-grade refractory materials, abrasives and metallurgical raw materials.
(1) As an abrasive, it can be used as an abrasive tool, such as grinding wheel, whetstone, grinding head, sand tile, etc.
(2) As a metallurgical deoxidizer and high temperature resistant material.
(3) High-purity single crystals can be used to manufacture semiconductors and silicon carbide fibers. Main Applications: For 3-12 inch monocrystalline silicon, polysilicon, potassium arsenide, quartz crystal and other wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
Used in semiconductor, lightning rod, circuit components, high temperature applications, UV detector, structural materials, astronomy, disc brake, clutch, diesel particulate filter, fine wire pyrometer, ceramic film, cutting tools, heating elements, nuclear fuel, jewelry, steel, protective gear and other fields
