摘要：Glasses with compositions 50Bi2O3-xSb 2O3-10B2O3-(40-x) SiO2 (x=0, 1, 3, 5, 8, 10) have been prepared by conventional melt quench technique. Substitution of Sb2O3 for SiO2 exerted an obvious effect on properties of glasses, especially, increased glass transition temperature (Tg) and crystalline temperature (Tc) greatly. Results of infrared transmission spectra attributed the effect to the formation of new bridging bonds of Sb-O-B and Sb-O-Si in glass network. ? 2009 The American Ceramic Society.
