ISSN: 0562-1836. 1314-62-1 and 7446-07-3 are cas registry numbers of chemicals which are used as reagents here. DOCUMENT TYPE: Journal; General Review CA Section: 57 (Ceramics) A review, with no refs., of investigations on structure and properties of tellurite glasses during the last ]0 yr. The structures of TeO2, TeO2-V2O5, TeO2-MoO3, TeO2-SeO2, TeO2-B2O3, and TeO2-GeO2 glasses and their phase diagrams are discussed. Elec. cond. and optical properties are described. .

Glass formation in the system calcium oxide-barium oxide-boron oxide-tellurium dioxide

Glass formation in the system calcium oxide-barium oxide-boron oxide-tellurium dioxide. Ivanova, I. (Bulg.). Stroit. Mater. Silik. Prom-st., 24(8), 24-5 (Bulgarian) 1983.Several reagents with their cas registry numbers 7446-07-3 and 1304-28-5 are used here. CODEN: SMSIAO. ISSN: 0562-1836. DOCUMENT TYPE: Journal CA Section: 57 (Ceramics) Glass formation in the CaO-BaO-B2O3-TeO2 system was investigated in relation to its compn. On a lab. scale, samples contg. 20, 40, 60, and 80 mol% TeO2 were examd. The 5-g samples were melted at 800-1100°, homogenized 30 min, and cooled. Stable glasses were formed at ￡80 mol.% TeO2. Above this value, an uncontrollable decrease in transparency occurred. .
