Interfacial Reactions in the System of MnTe-H sub(2) O

The thermodynamically possible reactions in MnTe-H sub(2) O system at room temperature have been studied. The potential-pH diagram has been plotted assuming quasi-equilibrium on interfacial boundary. The possible mechanism of formation and the composition of a surface in dependence on electrode potential and pH have been discussed and the stable conditions for manganese telluride, i.e. the specific area in the diagram (pH from -2 to 14 and potential from -1.5...- 1.1 to -0.9...-0.6 V) have been found. The obtained results may help optimize the conditions for electodeposition of manganese telluride thin films and for liquid chemical etching for the formation of interfacial boundaries.
