Abstract

Glass formation and stability of calcium aluminate‐based glasses were assessed, qualitatively, by changing melt volumes and cooling rates. Stable glasses, obtained through the addition of sodium, barium, and strontium to the binary system, were investigated in detail. Glass stability was evaluated via DTA analysis. The crystallization products were determined by X‐ray diffraction techniques. In addition, IR spectroscopic measurements were performed to gauge the relative water contents of the glasses and to assess the influence of composition upon the IR cutoff. It was determined that such additions greatly improve the glass‐forming ability and do not appear to negatively impact the optical properties of the glass. Copyright © 1993, Wiley Blackwell.
