The carbothermic reduction process is the attractive method for the low-cost production from oxides.
In the case of carbothermic reduction process of silica, the silicon carbides have an important role as intermediate product to increase the ratio of SiO gas.
In this study, we investigated the Effect of aluminum carbides on carbothermal reduction of alumina.
The adding of alumina carbides caused the increase of the aluminum product.
We will discuss the role of intermediated products of oxy-carbides and Al₂O gas.
