Abstract

The formation ranges of glasses in Mn02—Li20—P305 system have been experimented. The glass structure, valence and coordination number of manganese have been investigated by X—ray photo— electrical spectroscopy(XPS) infrared spectroscopy(IR) Rarnan spectroscopy and visible spectro scopy. The results have shown that some Mn ions iiay be in four-fold coordination and enter the glass network. Valence and coordination number of manganese and colour have also been discussed. The mang anese(1I) is pale yellow and is six-fold octahadron coordination. The manganese(Ill) is purples bluish—pink or brown and is predominantly in six—fold coordination. However the Mn—O bonds be— come more covalent with increasing Mn02 or MrtO2—Li20 content in MnO2-P2O and Mn02-Li20—P205 system.
