Antimony ingot is an ingot product of metallic antimony, which is a truncated pyramid hexahedron. It is stipulated that the weight of the ingot is not more than 25 kg, and its surface is smooth, without molten ballast, and has a star-shaped pattern. One of the commonly used non-ferrous metals of antimony, the pure metal antimony is rarely used alone. In addition to electroplating, other metals are used as the base to form alloys. It is the raw material for indirect production of antimony white. Due to its properties, metal antimony is rarely used alone except for electroplating. It is often used as a matrix to form various alloys to increase its hardness and strength.
The common metal antimony has a silver-white appearance and a purple-blue metallic luster on its section. Unlike ordinary metals, it is brittle, fragile, non-ductile, and can be ground into powder. Antimony is a poor conductor of heat and electricity. The melting point is 630.5°C and the boiling point is 1635°C. Antimony is a relatively stable metal. According to measurements, there is no obvious oxidation phenomenon when heated in the range of 100-250℃. Antimony is insoluble in water and stable in both dilute hydrochloric acid and concentrated hydrofluoric acid.
There are more than 200 kinds of antimony-containing alloys of industrial significance, of which the larger consumption of antimony is used to make battery lead grids and joint parts, bearing bushes, antimony bronze, movable type gold, cable armor, lead plates, lead pipes and Lead foil, solder, bomb, white wax, etc. The largest consumption is used as the raw material for indirect production of antimony white.
The production methods of antimony ingots are divided into two categories: fire method and wet method. At present, fire method is still the main method. The fire method is divided into direct smelting and volatile roasting (smelting)-reductive smelting and refining methods. Because all kinds of direct smelting methods have certain limitations, the volatile roasting (smelting)-reductive smelting and refining process will still be Maintain a major position in antimony metallurgy. In China, antimony trioxide is produced first by volatilization smelting in the blast furnace of volatilization roasting in the straight well furnace, and then reduced smelting in the reverberator to reduce antimony trioxide to crude antimony, and then refined antimony is produced by removing the harmful impurities in the crude antimony by refining.
