A new method to accurately and quantitatively study the chemical durability of glass was put forward. 提出了一種精確定量地研究玻璃化學(xué)穩(wěn)定性的新方法。
Due to their poor chemical durability, it is proposed to coat a layer of organosilicon (with 97% visual light reflectance) on the glass surface which will dramatically improve their chemical duration. 這類(lèi)玻璃的化學(xué)穩(wěn)定性較差，儅表麪塗以可見(jiàn)光反射率爲(wèi)97％的有機(jī)矽層後，穩(wěn)定性顯著提高。
The key of improving the chemical durability of non fluoride halide glasses is to introduce less soluble components into the glasses. 引入難溶組分是提高非氟鹵化物玻璃化學(xué)穩(wěn)定性的關(guān)鍵。
