Non-metallic aluminum by electrolysis (1) Low halide method (Gross method). In the method, the raw ore of aluminum is reduced to a crude aluminum alloy by a suitable method (for example, by the following carbon reduction method), and the vapor reaction of AIX3 (X is C1, F, etc.) is called at a high temperature to vaporize aluminum into Alx. Then, the cold robbery reverse reaction produces pure aluminum, and the generated AIX3 is used again and again. This reaction is called a burning reaction and is carried out as follows.

(2) Reduction method. It is a method in which a carbon reducing agent is mixed with a raw material such as alumina or bauxite, and aluminum or an aluminum alloy is obtained by reduction at 2270 K or more. In this method, there is a method in which A14C3 is used to reduce A12O3, a method in which AL4C3 is decomposed under high temperature and a reduced pressure, and a method in which Al2OC is then subjected to thermal decomposition. The well-known method of reducing metals is the Totb method of reducing AIC1 with manganese . In addition, there are also proposals for pyrolysis of human IN or aluminum alkyl.
