Antimony oxide is known as a network-former of glass. There are, however, few reports on this glass and most of those include some other network-former oxide or intermediate oxide.
In this paper, the determination of the glass forming region and the measurement of X-ray fluorescence spectra and infrared spectra are carried out to clarify the structure of glass in binary antimonate system with alkali and alkaline earth oxide.
Glass is obtained in the Li2O, Na2O, K2O, CaO, SrO, BaO-Sb2O3 system, but not in the MgO-Sb2O3 system and the Sb2O3 single oxide. From the measurement of X-ray fluorescence spectra and infrared spectra, the structure of the antimony complex anion in these glasses is identified as the same structure as stibiotantalite type which consists of tri-valent and penta-valent ions in the same amount.
