2 non-electrolytic metal aluminum
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.
It is a white inorganic pigment with non-toxic, best opacity, best whiteness and brightness, and is considered to be the best white pigment in the world today. Titanium white has strong adhesion, is not easy to change chemically, and is always white. Widely used in coatings, plastics, papermaking, printing inks, chemical fiber, rubber, cosmetics and other industries. It has a high melting point, and is also used to make refractory glass, glaze, enamel, clay, high temperature resistant laboratory utensils, etc.
Anatase titanium dioxide belongs to pigment grade titanium dioxide, which has the characteristics of strong hiding power, high coloring power, and good weather resistance. Mainly used in industrial sectors such as rubber, plastics, papermaking, printing inks, coatings and chemical fibers.
The use of anatase titanium dioxide mainly has the following aspects: Titanium dioxide for papermaking generally uses anatase titanium dioxide without surface treatment, which can play the role of fluorescence and whitening, and increase the whiteness of paper. The titanium dioxide used in the ink industry has rutile type and anatase type. It is an indispensable white pigment in advanced inks. The titanium dioxide used in the textile and chemical fiber industries is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide is not only used as a coloring agent in the rubber industry, but also has reinforcing, anti-aging, and filling functions, and is generally based on anatase.

(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.
