Abstract

Phosphate glasses are materials able to incorporate many different oxides such as MoO3, B2O3, V2O5, and Fe2O3 in their composition, valuable for electronics, optoelectronics, agriculture, etc. The paper presents the study of vitreous materials based on phosphate glass matrix to which 1-7 mol % of MoO3, B2O3, V2O5, and Fe2O3 were added. Glass was prepared by melting the raw materials in electric furnace at 1150 - 1250 o C for 2h using ceramic crucibles. In order to establish phosphate glasses solubility, the conductometric method was used. Glass structure was analyzed by FTIR and Raman spectroscopy. Analyzes of glasses microstructure, composition and homogeneity were made by using energydispersive X-ray spectroscopy microanalysis - EDAX and scanning electron microscopy - SEM..
