The binder for silicon carbide is made from white polymer, with a mere 1% addition. It improves the hydrophilicity and has a strong bonding function with silicon carbide raw material. Quartz sand, wood chips, salt, coke and anthracite are used as raw materials to make silicon carbide. It is then melted at a high temperature in a resistence furnace. Purity and particle size are important factors for the silicon carbide (SiC) to enter furnace raw materials. If not, it will cause problems like poor gas permeability in the furnace charge or incomplete reaction between C and SiO2. In order to avoid the problem of too fine raw materials being fed into the furnace, the charge must be enriched with a high-purity binder. This is then processed into smelting granules. It is used in the smelting process of silicon carbide. This helps to improve the gas permeability, finish the reaction between C & SiO2, and reduce emissions. This is the most effective way to reduce costs.
