Effect of the temperatures on structural and optical properties of tin oxide (SnOx) powder

A series of composite SnOx materials were prepared by SnO powder heating at different temperatures in air for 2 hr. Depending on treatment conditions it was found that SnO, with its tetragonal structure, could transform into the Sn phase or tetragonal SnO and tetragonal SnO2. The influence of heating at different temperatures on the properties of SnOx has been studied. The influences of annealing temperatures in air on the structural and optical properties of SnOx have been investigated. Correlations between the structural and optical properties of the products were found.
