Is there any information about elemental antimony?

In which part of the process in which the antimony content in the cloth is generated.

The encyclopedia is very detailed, and all the information is available.

The use of antimony: 1. It is to use its oxide (antimony trioxide) to make refractory materials. 2. It is used in the field of biology or medicine. 3. High-purity antimony and antimony metal compounds (indium antimony, silver antimony, gallium antimony, etc.) are also ideal materials for the production of semiconductors and thermoelectric devices.

The content of antimony in the earth's crust is mainly in the form of elemental or stibnite, galenite, antimony and antimony ochre, and there are as many as 120 known antimony-containing minerals. Antimony is a silvery-white, shiny, hard and brittle metal with a scaly crystal structure. It gradually loses its luster in moist air and burns into an oxide of white antimony in strong heat.

Since the end of the 20th century, China has become the world's largest producer of antimony and its compounds, most of which in turn comes from tin mines in Lengshuijiang, Hunan Province.

Antimony is not a very reactive element, it only reacts with water when it is red hot to release hydrogen, which will not be oxidized by air at room temperature, but can be combined with fluorine, chlorine and bromine; When heated, it can be combined with iodine and other 10 metals.

With the development of science and technology, antimony has been widely used in the production of various flame retardants, alloys, ceramics, glass, pigments, semiconductor components, pharmaceuticals and chemical industries. Antimony is used for the production of flame retardants accounts for about 60% of the total antimony consumption, about 20% is consumed in the manufacture of alloying materials, plain bearings and fluxes in batteries, and about 20% in other aspects.

The main use of antimony is its oxide (antimony trioxide) in the manufacture of refractories. The process by which antimony trioxide forms halides of antimony can slow down combustion.

In addition to halogen-containing polymeric flame retardants, antimony trioxide is almost always used in conjunction with halide flame retardants. These flame retardants are often used in children's clothing, toys, aircraft and car seat covers, etc., and are also commonly used as additives for polyester resins in glass fiber composite materials i, commonly known as glass fiber reinforced plastic) industry, such as engine covers for light aircraft.

Antimony is a poor conductor of electricity and heat, which is not easy to oxidize at room temperature and has anti-corrosion properties. Therefore, the main role of antimony in alloys is to increase hardness, and it is often used as a hardener for metals or alloys.

Antimony-containing lead-based alloys are corrosion-resistant, and are the preferred materials for the production of electrode plates, chemical pumps, chemical pipelines, and cable claddings for vehicles and ships. Antimony, an alloy of tin, aluminum, and copper, is a strong and wear-resistant alloy, making it an excellent material for the manufacture of bearings, bushings, and gears.
