Change in Plasticity of Ag2S during the Transition from the Monoclinic to the Superionic Cubic Phase

Abstract

The temperature dependence of the microhardness of Ag₂S is measured in the temperature range of the transition from the monoclinic to the cubic crystalline modification. The obtained experimental data are discussed, taking into account the anomalously high plasticity of this compound and the superionic nature of its cubic modification.
