Emery

Emery also known as silicon carbide (SiC), is made by high-temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), and sawdust (salt needs to be added when producing green silicon carbide) through a resistance furnace. Silicon carbide also exists in nature as a rare mineral, moissanite. Silicon carbide, also known as carbon silica. In contemporary high-tech refractory materials such as C, N, and B, silicon carbide can be referred to as steel sand or refractory sand. Application of Emery: (1) As an abrasive, it can be used to make grinding tools such as grinding wheels, oilstones, grinding heads, sand tiles, etc. (2) As a metallurgical deoxidizer and high-temperature resistant material. (3) It can also be used for polishing and grinding hardware, glass, gemstones, jade, and other items. Silicon carbide has four main application areas, namely functional ceramics, refractory materials, abrasives, and metallurgical raw materials.
