Abstract
A series of composite SnO sub(x) 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 SnO sub(2). The influence of heating at different temperatures on the properties of SnO sub(x) has been studied. The influences of annealing temperatures in air on the structural and optical properties of SnO sub(x) have been investigated. Correlations between the structural and optical properties of the products were found.
