【摘要】 <正> 磷酸盐玻璃的性质和形成规律的研究比硅酸盐玻璃少得多。由于磷酸盐玻璃的化学稳定性比普通硅酸盐玻璃差,原料价格高等因素,降低了它的实用性。但是磷酸盐玻璃具有某些特殊性能是其他系统玻璃不能达到的,若对特定的磷酸盐系统作适当成分调整后,仍可以获得基本性质较好,有实际应用价值的特种光功能玻璃,如激光介质材料和特种光学更多还原

【Abstract】 A study on primary characteristics of B2O-BaO->P2O5 system was carried out by which the glass forming area and the dependence of glass composition on coefficient of thermal expansion,density at room temperature,transition temperature,softening temperature,range of crystallization temperature,high temperature viscosity and chemical durability were obtained.更多还原
