Expert Reviews

Dr. Marcus Tägtmeyer (International Medical and Technological University, Dar es Salaam, Tanzania)

Antimony pentoxide powder is insoluble in nitric acid but dissolves in a concentrated potassium hydroxide solution. Antimony pentoxide finds use as a flame retardant and other plastics and as a flocculant in the fabrication of titanium dioxide and is sometimes used in the production of glass, paint, and adhesives. It is also utilized as anion exchange resin for a number of cations in acidic solution involving Na+ (especially for their selective retentions), and as polymerization and an oxidation catalyst.

Dr. Ms Jane Li (National Penghu University of Science and Technology, Magong, Penghu,  Republic of China)

Antimony pentoxide powder is a metalloid (i.e., possesses electronegativity and ionization energy properties. It is primarily used as a plastic catalyst in the manufacture of polyethylene terephthalate (PET) plastic as well as in combination with halogenated compounds as a synergist to enhance flame-inhibiting properties. Antimony alloys are also utilized in batteries, low friction metals, type metal, and cable sheathing, among other products. The compounds of Antimony are used to make flame-proofing materials, ceramic enamels, paints, glass, and pottery.

Dr. Willem-Jan de Kleijn Ph.D (Luleå University of Technology, Luleå, Sweden)

Antimony pentoxide powder: Polyvinyl chloride (PVC) is an inherently inflammable halogenated polymer to which antimony trioxide may be added to improve flame retardant properties, particularly when flammable plasticizers are added. As a flame retardant, antimony trioxide may be added to PVC and non-PVC plastics, textiles, and rubbers. Typically, these products find use in electrical equipment, wires, automotive parts, some building materials, and packaging.

Dr. JKF Gojukai PhD  (Kaiserslautern University of Technology, Kaiserslautern, Rhineland-Palatinate, Germany)

Antimony pentoxide powder: Flame retardants containing antimony oxide are used in commercial and household items, including furniture, carpets, mattress covers, draperies and textiles, paper and plastic. In addition, antimony oxide is used in enamels for ceramics and plastics, pigments in paint and ceramics, and stabilizers in glass, rubber, and adhesives. The compound of antimony is antimony sulfide which is employed in the heads of some safety matches.  In addition, Antimony is utilized in bullets, bullet tracers, paint, glass art, and as an opacifier in enamel.

Dr. Huang Fu Ph.D  (Maebashi Institute of Technology, Maebashi, Gunma, Japan)

Antimony pentoxide powder: It is utilized in the electronics industry to make some semiconductor devices. It is alloyed with lead or other metals to enhance their hardness and strength. A lead-antimony alloy is used in batteries. Other uses of antimony alloys involve type metal (in printing presses), bullets and cable sheathing. Antimony is mainly employed as the trioxide for flame-proofing compounds.
