Abstract
The present invention relates to a metal oxide particle comprising tin atom, zinc atom, antimony atom and oxygen atom, having a molar ratio SnO2:ZnO:Sb2O5 of 0.01–1.00:0.80–1.20:1.00 and having a primary particle diameter of 5 to 500 nm; and a process for producing the metal oxide particle comprising the steps of: mixing a tin compound, a zinc compound and an antimony compound in a molar ratio SnO2:ZnO:Sb2O5 of 0.01–1.00:0.80–1.20:1.00; and calcining the mixture at a temperature of 300 to 900° C. The metal oxide particle is used for several purposes such as antistatic agents, UV light absorbers, heat radiation absorbers or sensors for plastics or glass, etc.
