Synthesizer for high-purity silicon carbide powder

The invention discloses a synthesis device of high-purity silicon carbide powder. The synthesis device comprises a crucible; the stock bin is arranged in the crucible and fixed to the top of the crucible, a loading area is defined between the stock bin and the crucible, and a partition vertical plate is arranged in the loading area; the silicon material opening and closing door is used for opening or closing the silicon material outlet, and the carbon material opening and closing door is used for opening or closing the carbon material outlet; a material homogenizing bin; a primary scraper is arranged at the top end of the rotating shaft; the driving motor drives the first-stage scraper and the second-stage porous plate to rotate synchronously through a rotating shaft; the plurality of second-stage scrapers are positioned above the second-stage perforated plate; the side heater group comprises a plurality of stages of resistance type heating rings, and each stage of resistance type heating ring is independentl
