PREPARATION OF PLATINUM-FREE LASER GLASS

Abstract

The purpose of this project is to produce high optical quality laser glass free of platinum particles. It was found that glass melted under an inert atmosphere in a platinum crucible contained no detectable platinum particles. Methods to prevent evaporation of various oxides that caused inhomogeneities in the glass were investigated. Data was accumulated to determine the effect of time, temperature, and atmosphere on the weight loss of platinum and alloying of platinum with ingredients in glass. A parallel approach to this problem is the melting of glass in a high purity all ceramic system. Modifications of the system, based on results of the initial runs, have been completed. Failure of a high temperature sprinkler head during testing of the furnace has seriously delayed this phase of the project. (Author)
