Abstract

Influence of chemical composition of nickel tellurides Nil+p Te2(O p 1.5) on oxidation during heating up to 900°C in air was investigated by thermal,X-ray and electron diffraction analysis.

As a first oxidation step Nil+p Te2 compounds with p O give rise to NiO and NiTe2 phases. At higher temperatures, NiTe2O5 and Ni2Te3O8 are formed, which oxidizes above 600°C to Ni3TeO6. This decomposes above 900°C leaving NiO as a final solid product. Formation of oxidized layers significantly slows down the kinetics of the oxidation processes.
