Silicon carbide is also called emery or refractory sand. Silicon carbide is smelted at high temperature in a resistance furnace with raw materials such as quartz sand, petroleum coke, and wood chips. At present, the silicon carbide produced in my country is divided into black silicon carbide and green silicon carbide. Silicon carbide has been recognized by the market in terms of cutting and grinding. After continuous promotion and use, the application of silicon carbide has been more and more valued by the market.
The hardness, particle shape, particle size, circularity and powder content of silicon carbide micropowder play a vital role in cutting; the application of silicon carbide is also determined by the hardness of raw materials. At the same time, the smelting process, smelting time , Will seriously affect the quality of silicon carbide.
If silicon carbide is too hard or too soft, it will seriously damage the product when using silicon carbide as a cutting material. It will cause the silicon carbide particles to be ground and passivated, resulting in a decrease in cutting force. cause damage to the product. Therefore, the quality of silicon carbide products must be guaranteed when selecting products.
In addition, in the production of silicon carbide sand and silicon carbide powder, the model and particle size must be uniform. The use of machines or screens is to ensure that the particle size of silicon carbide sand is uniform, so as to better ensure the quality of the product. For example, silicon carbide micropowder is the most important abrasive in multi-wire cutting silicon wafers, and is often used to cut hard and brittle materials.
