Overview
Antimony oxide may refer to any of the following:
- Diantimony tetroxide, Sb2O4
- Antimony trioxide, Sb2O3
- Antimony pentoxide, Sb2O5
- Antimony hexitatridecoxide, Sb6O13
- Stibiconite, Sb3O6(OH)
Antimony tetroxide is an inorganic compound with the formula Sb2O4. This material, which exists as the mineral cervantite,[3] is white but reversibly yellows upon heating. The material, with empirical formula SbO2, is called antimony tetroxide to signify the presence of two kinds of Sb centers.
Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis. A mixed arsenic-antimony oxide occurs in nature as the very rare mineral stibioclaudetite.
Antimony pentoxide (molecular formula: Sb2O5) is a chemical compound of antimony and oxygen. It contains antimony in the +5 oxidation state.
Stibiconite is an antimony oxide mineral with formula: Sb3O6(OH). Its name originates from Greek stíbi (στίβι), 'antimony' and kónis (κόνις), 'powder', alluding to its composition and habit. It is a member of the pyrochlore super group.
Manufacturing Process
Antimony oxide nanoparticles can be synthesized using polyvinyl alcohol in water solution via reaction between antimony trichloride and sodium hydroxide. The nanoparticle created is 10 to 80 nm in size. High-resolution electron microscopy (HREM) and transmission electron microscopy can be used to characterize the microstructure of these nanoparticles.
Application
The key applications of antimony oxide nanoparticles are listed below:
- In high conductivity applications
- As an antistatic additive and a flame retardant in coatings, nanowires, plastics, fiber and textiles
- In some alloy and catalyst applications
- In electrochromics or electro-optics and magnetic machines and micro-equipment due to their high conductivity
