Introduction

This article discusses the properties and applications of antimony tin oxide nanoparticles. Antimony is a Block P, Period 5 element, Tin is Block P, Period 5 element, and oxygen is a Block P, Period 2 element.

Antimony tin oxide is an alloy of tin (IV) oxide doped with antimony pentaoxide. It has extremely high conductivity. Tin:antimony ratios are typically between 80:20 and 95:5. The material forms crystalline nanoparticles which have a variety of applications, mainly in alloys and composites due to their good electrical properties.

The morphology of antimony tin oxide nanoparticles is spherical, and they appear as a blue powder. Antimony tin oxide nanoparticles can cause serious eye and skin irritations.
