<p>A method for removing a surface layer from a metal fluoride glass containing barium ions, particularly glass rods of the type used for manufacturing fibers for optical communications technology. A rapid, uniform and turbidity-free erosion of a disturbed outside layer of the starting glass is accomplished with an etchant solution in which a fluoride complexing agent or a barium complexing agent is dissolved. In particular, a rapid dissolving of a barium fluoro-zirconate glass is achievable with an etchant solution containing acidic Zr (IV) salts, whereby the risk of contaminating the so etched surface by the etchant solution does not exist.</p> |
