Reduction of Kaolin would then result in an aluminum/silicon alloy. In practice, carbides usually SiC resist further reduction except at very high temperatures 2050 C . Thus, the smelted product is likely some aluminum-rich alloy with various highly refractory simple and complex carbides. Halman tests suggest that product are aluminum and silicon carbides, not pure metal/alloy Parent material is reduced carbothermically, that is, it is reduced in the presence of carbon and the absence of oxygen at high temperatures. The carbon is oxidized to produce carbon mon- and di-oxide and the metal oxides are reduced but converted to carbides .
