Nanoparticles research is gaining increasing interest due to their unique properties, such as having increased electrical conductivity, toughness and ductility, increasing the hardness and strength of metals and alloys, formability of ceramics, luminescent efficiency of semiconductors.
This article discusses about the properties and applications of antimony oxide nanoparticles. Antimony is a Block P, Period 5 element, while oxygen is a Block P, Period 2 element.
The morphology of antimony oxide nanoparticles is spherical, and they appear as a white powder. Antimony oxide nanoparticles are graded as harmful with a possibility of causing cancer.
The chemical properties of antimony oxide nanoparticles are outlined in the following table.
||Antimony [Kr] 4d105s2 5p3
Oxygen [He] 2s2 2p4
The physical properties of antimony oxide nanoparticles are given in the following table.
The thermal properties of antimony oxide nanoparticles are provided in the table below.
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.
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
