  • Internal oxidation of an Ag-1.3at.%Te alloy
    Kosec, Ladislav ...
    The internal oxidation an Ag-1.3at.%Te was studied at 750, 800 and 830 $^{\circ}$ in pure oxygen (1 atm). The internal oxidation under such high oxygen pressure resulted in formation of two different ... types of oxide particles and two different fronts of internal oxidation in the internal oxidation zone. The coarser Ag_2TeO_3 particles were formed through the in situ internal oxidation Ag_2Te particles and the tiny oxide precipitates (most probably also Ag_2TeO_3) were formed through internal oxidation of tellurium from solid solution. Considering the mechanism of internal oxidation, both diffusionless and diffusive modes were found to be present simulataneously in the oxidation of Ag-1.3at.%Te alloy. These results were examined with regard to the solubility of tellurium in silver, which was foundto be 0.1at.%Te at 750 $^{\circ}$C and 0.26at.%Te at 830 $^{\circ}$C, as well as the presence and disolution of Ag_2Te particles.
