Regularities of the Transition from a Bi–Te Metal System to a Bi2O3–TeO2 Oxide System upon Oxidation

The regularities and process of glass formation upon the transition from a Bi–Te metal system to a Bi 2 O 3 –TeO 2 oxide system are studied with the use of oxidation of the corresponding metal alloys. The process of oxidation and the oxidation state of the alloys depending on temperature and time are studied by gravimetric analysis. The formation of minima in the dependences of the oxidation rates of the alloys is interpreted as the transition of the process from a diffuse region to a region of chemical kinetics.
