Effect Of Melting Atmospheres On The Structure And Properties Of P2o5-Sno2 Glass Systems

In this study, tin phosphate glass system(SnO2-(1-x)P2O5-xB(2)O(3)) that occur during the melting of the metal oxide inhibition of the oxidation reaction, and to reduce oxides of high melting temperature in the following three methods were melting. The first is the general way in the atmosphere, and the second by injecting N-2 gas under a neutral atmosphere, and finally in the air were melted by the addition of a reducing agent Melt in the atmosphere when the oxidation of the metal oxide is inhibited by low temperatures were melting. In addition, the deposition of crystals within glassy or inhibit devitrification phenomenon is also improved over 80% transmittance. This phenomenon, when the melting of glass, many of Sn4+ ions are reduced to the Sn2+ was forming oxides SnO, because it acts as a modifier oxide.
