1. Flame retardant: The main use of antimony is to use its oxide (antimony trioxide) to make refractory materials. The process by which antimony trioxide forms antimony halides can slow down combustion. In addition to halogen-containing polymeric flame retardants, antimony trioxide is almost always used with halide flame retardants. These flame retardants are often used in children's clothing, toys, aircraft and car seat covers, etc. They are also commonly used as additives for polyester resins in the fiberglass composite (commonly known as FRP) industry, such as light aircraft engine covers.

Recently, the price of antimony ingot in Europe has stabilized at US,600-14,200/ton, up 45% from August last year; the harm to the environment and human body caused by antimony smelting has forced the government to strictly control its output. The antimony industry was reorganized by the joint efforts of the departments. Hundreds of illegal antimony smelters and small and medium-sized workshops were forcibly banned, resulting in a sharp reduction in the antimony market supply.
