【 摘 要 】

Crystallization studies are carried out under non-isothermal conditions with samples heated at several uniform rates. The dependence of the glass transition temperature (�??_�??), the crystalline temperature (�??_�?) and the peak temperature of crystallization (�??_�?) on the composition and heating rate (�?) has been studied. For a memory/switching material, the thermal stability and ease of glass formation are of crucial importance. The glass transition temperature, �??_�??, increases slightly with the variation of Bi content. From the heating rate dependence of �??_�??, the activation energy for glass transition (𝐸_�?) has been evaluated. The results are discussed on the basis of Kissinger’s approach and are interpreted using the chemically ordered network model (CONM).
