Antimony Trioxide, a natural product called antimony white, is a white crystalline powder. It turns yellow when heated and turns white when cooled. It has no odor, with a melting point of 655℃ and a boiling point of 1550℃.
It can sublime when heated to 400℃ in a high vacuum. It is soluble in sodium hydroxide solvent, hot tartaric acid solvent, tartaric acid solution and sodium sulfide solvent, and slightly soluble in water370±37μg/L, dilute nitric acid and dilute sulfuric acid. So what are its applications? Let's learn about it together.
Antimony Trioxide can be used as an excellent inorganic white pigment, white glass, enamel, medicine, cement, filler, mordant and fire retardant coating, etc. It is a good covering agent used to make mordants and opalescent agents. Antimony Trioxide is a "star" among flame retardants. It is widely used in plastics, rubber, textiles, chemical fibers, pigments, paints, electronics and other industries. It is also used as a catalyst and production raw material in the chemical industry. In the field of flame retardancy, the quality of antimony trioxide is strictly required.
In addition to basic indicators such as composition, whiteness and black spots, particle size and surface properties are also key factors. Particle size has a significant effect on the chromaticity and mechanical strength of organic polymers, while surface properties determine whether antimony trioxide can be evenly dispersed in the polymer to obtain the best flame retardant effect. In order to prepare micron or even nanometer antimony trioxide, new grinding machines such as mechanical ball mills and cell mills are required.
These devices can control the particle size according to the characteristics of antimony trioxide, thereby obtaining high-quality and effective grinding effects. In the chemical industry, Antimony Trioxide is used as a high-purity reagent, mordant and light-proof agent, and is also used in the preparation of pigments and potassium antimony tartrate. It can also be used as a flame retardant for various resins, synthetic rubber, canvas, paper, coatings, etc., and a catalyst for petrochemicals and synthetic fibers. It is used to make mordants and opacifiers, and is a raw material for synthesizing antimony salts. In the enamel industry, Antimony Trioxide is used as an additive to increase the opacity and surface gloss of enamel. In the glass industry, it is used as a decolorizer to replace arsenous acid. It is widely used in medicine, metallurgy, military industry, etc.
Antimony trioxide is an important flame retardant and is widely used in industries such as plastics, electronics and cables. PE, as a carrier material, has good plasticity and dispersibility, and can effectively disperse antimony trioxide in products to improve the flame retardant effect and stability of products. In short, the application of antimony trioxide in the field of flame retardancy is wide and important, and the optimization of its quality and performance is of great significance to improving the flame retardant effect and reducing costs.
