Abstract: GLASS COMPOSITIONS ARE DISCLOSED WHICH HAVE LOW THERMAL EXPANSION CHARACTERISTICS AND EXCELLENT INFRARED AND ULTRAVIOLET OR RADIO FREQUENCY TRANSMITTANCE CHARACTERISTICS. THESE COMPOSITIONS ARE USEFUL IN MANUFACTURING DOMES SUITABLE FOR HOUSING INFRARED AND ULTRAVIOLET OR RADIO FREQUENCY DETECTORS SUCH AS ARE USED IN MISSILE SYSTEMS. THE GLASSES ARE BASICALLY GERMANIUM OXIDE GLASSES INCLUDING SUITABLE AMOUNTS OF ALKALI OXIDES, ZINC OXIDE, CALCIUM OXIDE, ZIRCONIUM OXIDE, ALUMINUM OXIDE AND OTHERS. THE ADDITION OF CERTAIN RARE-EARTH OXIDES, SUCH AS YTTERBIUM OXIDE, GIVE A DESIRABLE INCREASE IN SURFACE HARDNESS.
