摘　　要：在酸溶玻璃组成研究的基础上,通过扫描电镜、能谱仪及电感耦合等离子体光谱仪等测试,研究了硼硅酸盐玻璃的酸溶机理。结果表明：当SiO2与B2O3质量比为1：4时,玻璃的酸溶效果最好,且在H2SO4与HNO3的摩尔比为2：1的混合酸溶液中,玻璃的酸溶速率最快;在硼（B）含量低于61%时,B含量的提高有利于酸溶速率的增加。促进酸溶进行的两个要素是金属离子与H＋离子的交换和[BO3]与H2O的反应。The acid dissolving mechanism of boro-silicate glass was investigated by scanning electron microscopy, energy dispersive spectrum and inductively coupled plasma mass spectrometry, respectively. The results show that the acid solubility of boro-silicate glass is optimized when the mass ratio of SiO2 and B2O3 is 1：4. Also, the fastest acid dissolving rate of boro-silicate glass is achieved in a mixed acid solution of H2SO4 and HNO3 when the molar ratio of H2SO4 to HNO3 is 2：1. Increasing the B content before 61% is beneficial to acid dissolving. Two major factors, i.e., ion exchange occuring between metal and hydrogen ions and the chemical reaction between [BO3] and H2O, accelerate the process of acid dissolving.
