Abstract
Glass formation in three-component tellurite-phosphate and tellurite-borate vitreous systems has been determined, with the latter including metal oxides or metal halides (chloride, fluoride or bromide), respectively. The results obtained have served as a base for the determination of the glass forming tendency in a number of telluritemetaphosphate and tellurite-metaborate triple combinations. Hence a new family of tellurite glasses has been obtained. It has been established that the glass formation is most observed in alkaline, earth alkaline oxide and halide metaphosphate systems. The three-component tellurite-metaphosphate and metaborate systems investigated have been treated as partial three-component sections of the main four-component telluritephosphate and tellurite-borate systems also.
