摘要：The lead borophosphate glasses of general formula Pb 1-x Ca x BPO 5 (0≤ x≤ 0.5) were synthesized by conventional melting method. They were investigated by differential scanning calorimetry (D SC) and IR spectroscopy. The crystallization mechanism and kinetic parameters of crystal growth were evaluated using different model s. It was found that the CaO takes a prominent part on the stability and on the nucleation phase of the glasses. According to obtained thermal parameters, the crystallization mechanism of the glasses depends on the calcium content. The analyses of IR spectra show that the CaO causes a change and stabilizes some phosphate and borate units in the structure of the borophosphate.
