Silicon carbide is employed as being a raw component in a few glazes applied to ceramics. At high temperatures it could reduce metal oxides forming silica and carbon dioxide. In the resistance or electrical arc furnace, boric anhydride (B2O3) is carbothermically lowered at temperatures exceeding 2000°C to supply boron carbide. https://glass-lined-braided-steel37047.blogvivi.com/34998083/what-does-ti-carbide-mean
