Abstract

The glassy state, structure and some physico-chemical properties of phosphate glasses on the basis Ba(P03)2 have been determined. The synthesis of the glasses was curried out in crucibles of glassy coal and corundum in an electric furnace in argon atmosphere. On the basis of the absorption spectra in infrared and Raman spectra the structural groups occurring in the phosphate glasses were determined. The addition of the oxides of bivalent metals to the glassy metaphosphate of barium leads in the first phase to breaking of chain metaphosphate particles, their decay and to the formation of pyrophosphate particles. The addition of Si02 results in the decrease of the polymerization degree of the aliphatic anions. The effect of replacing the oxides by fluorides and chlorides on the structure and properties of glasses has been also investigated. On the basis of the examinations of phosphate glasses the possibility of their application in fibre optics has been established. The compositions of phosphate glasses intended to be used for the cladding andcore of the optics fibres have been listed and the light pipes produced in the glass works "Bialystok" by the twocrucible method. The properties of the obtained optic fibres are defined.
