摘 要：<正>A series of new glass compositions based onPbX2（X: Cl, Br or I） have heen studied. Binary andternary glasses resulted from the association of PbI2 Pb-Cl2 AgI, KCl and KBr. By means of differential scan-ning calorimetry （DSC）, the mechanism and kinetics ofcrystallixation process were studied. X-ray diffractionstudies demonstrate that there is the formation of compli-cated crystalline phases in crystallized lead iodide basedglasses. By heat treating halide glasses of appropriatecomposition under adequate heating temperature and dura-tion, the lead iodide based glasses could be converted intoglass-ceramics with microcrystal size less lμm of whichmechanical properties are improved.
