Patent number: 10407307Abstract: Inside a furnace body with a vacuum environment or under the inert gas protection, the raw silicon material used to produce silicon carbide is melted or vaporized in a high temperature environment over 1300° C., and then the melted or vaporized raw silicon material will react with the carbonaceous gas or liquid to form silicon carbide. The present invention uses the carbonaceous gas with no metallic impurities, to replace petroleum coke, resin, asphalt, graphite, carbon fiber, coal, charcoal and some other carbon sources used in current production processes. When the carburizing reaction is in progress, the raw silicon material is melted or vaporized and the reaction takes place in the air. No container is required, so impurity contamination is lessened, and the produced silicon carbide has a fairly high purity.Type: GrantFiled: February 12, 2015Date of Patent: September 10, 2019Assignee: Taizhou Beyond Technology Co., Ltd.Inventors: Masahiro Hoshino, Lenian Zhang
