IR Transmitting Rare Earth Gallogermanate Glass-Ceramics.

Abstract

A glass-ceramic article or composition which has better thermal and physical properties than the competing materials of zinc sulfide, spinel, or magnesium fluoride comprising 2-30 mole percent yttrium oxide and/or rare earth oxide, 25-80 mole percent germanium oxide, and 5-30 mole percent gallium oxide, based on the total moles of yttrium oxide and/or the rare earth oxide, germanium oxide, and gallium oxide; which article is over 80% by volume crystalline.
