Carbothermic Reduction - an overview

Unlike the Hall–Héroult process, carbothermic reduction is a nonelectrolytic reaction, where alumina reacts with carbon to form aluminum and CO (Fig. 8.9). The process requires high temperature (2000°C), which is achieved through multichambered furnace (White et al., 2012).

Carbothermic Reduction - an overview

Carbothermic reduction is the most widely used process for preparing nitride fuel. The starting material is a dioxide and carbon, and the general reaction is expressed as [I] MO 2 + 2 C + 0. 5 N 2 = MN + 2 CO. where M represents an actinide element, such as U and Pu. The mixture of dioxide and carbon is heated in N 2 gas stream, usually at 1773–1973 K. It is considered that the carbothermic ...
