摘要: 通过添加重金属钡的酸碱溶液, 在不同外界条件下, 研究了磷酸盐激光玻璃表面结构在酸碱侵蚀过程的反应机理. 结果表明, 酸碱对磷酸盐激光玻璃的侵蚀过程主要包括金属阳离子析出和[PO4]网络结构破坏等两个重要过程. 金属阳离子的析出主要是非桥氧结构P-O-M(M为K+、Ba2+、Al3+等阳离子)在酸碱作用下生成P-O-H基团, 而[PO4]网络结构的破坏则是指玻璃网络原有的Q2结构在酸碱的侵蚀下逐渐向Q1和Q0转变. 据此, 推导了磷酸盐激光玻璃在酸碱侵蚀过程中的反应模型.

Abstract: The effect of chemical etching processes on phosphate laser glass surfaces was investigated. Under different process conditions (e.g. sonication and agitation), conventionally polished and subsequently washed phosphate glass plates were treated by submerging in both HCl and KOH solution either with or without BaCl2. Subsequently, Raman spectra and X-ray photoelectron spectroscope (XPS) of the treated surfaces were measured. The precipitation of metal cations and depolymerization of the glass network structure are the two main chemical reactions in both solutions: One refers to the substitution of P-O-H for P-O-M, the other is that the Q2 tetrahedra, the basic structural unit of the original metaphosphate glass, has gradually been replaced by the Q1 or Q0 tetrahedra. Finally, the reaction models of phosphate laser glasses dissolved in both HCl and KOH solution are proposed.

Key words: phosphate glass, etching, Raman spectra, XPS
