Briquette method of waste SiC from silicon wafer sludge and additive for casting thereby

It relates to a single photochemical method of closed-SiC powder and Briquetting additives for casting according thereto, transferring the SiC powder generated as a waste in the silicon wafer sludge and storage to easily and to have a suitable strength and density for use as a cast additives having a high yield It will be possible to stage mineralization. The present invention includes the steps of collecting the SiC powder from silicon sludge generated in a silicon wafer cutting process, and; Adding an Fe powder as the binding agent of the SiC powder and; The method comprising applying pressure to the mixed powder of the Fe powder is added to the SiC powder molded into a shaped body and; Characterized by including the step of sintering the molded body molded in the previous step.
