摘　　要：将Ｐ２Ｏ５－ Ｂ２Ｏ３－ Ａｌ２Ｏ３－ ＭｇＯ－ Ｋ２Ｏ玻璃在２００～２８０℃温度下处理４～１２ ｈ。处理与未处理的磷酸盐玻璃在７５ ％ 相对湿度和７０ ℃下加速风化３ ｄ。详细研究了风化程度的变化，表明热处理后的玻璃风化速率比未热处理玻璃的风化速率有所下降。The samples of P 2O 5-B 2O 3-Al 2O 3-MgO-K 2O glasses were treated at temperature of 200～280℃ for 4～12hours.Accelerated weathering tests on treated and non-treated phosphate glasses have been made under static conditions of 75% relative humidity at 70℃ for 3 days. Detailed studies of the change of weatherability show that the weathering rate of heat treatment sample is less than that of nontreatment sample.
