Non-electrolytic aluminum

[China Aluminum Industry Network] Non-electrolytically Processed Metal Aluminum (1) Low-cost Halide Method (Gross Method). The method is to reduce the aluminum ore to a crude aluminum alloy by an appropriate method (for example, using the following carbon reduction method), and at a high temperature, it is called AIX3 (X is C1, F, etc.) vapor reaction to convert aluminum to Alx. Then, cold robberies reversed to produce pure aluminum, and the resulting AIX3 was used repeatedly. This reaction is called burning reaction.

(2) reduction method. It is a method of mixing aluminum and bauxite with carbon reducing agents and reducing them to 2270K or more to produce aluminum or aluminum alloys. This method includes the method of reducing A12O3 by using A14C3 as a method, and the method of decomposing AL4C3 under high temperature and reduced pressure, and the method of pyrolyzing Al2OC into Al2OC.

The well-known metal reduction method is the Totb method using manganese to reduce AIC1. In addition, there are also pyrolysis solutions such as IN or alkyl aluminum.
