Abstract

The glasses of TeO2 – ZnO and TeO2 – WO3 system have been produced by melting the mixture of high-purity oxides in platinum crucible in the flow of purified oxygen with subsequent cooling of the melt. The total content of the impurities of transition metals in these glasses did not exceed 1 ppm wt. The content of platinum impurity is at the level of 5-100 ppm. The effect of temperature, time of synthesis and the concentration of water in oxygen, on the content of OH-group impurities in glasses was investigated. The samples of tellurite glasses are obtained with the factor of bulk optical absorption not more than 0.002 cm-1 at 3.0-3.2 μm..
