description: The purpose of this work is to study the effect of the composition of phosphate glasses: Na_2 O-La_2 O_3-P_2 O_5,Na_2 O-Al_2 O_3-P_2 O_5, Na_2 O-Y_2 O_3-P_2 O_5, La_2 O_3-Y_2 O_3-P_2 O_5,Eu_2 O_3-P_2 O_5 on a number of thermophysical properties. The research set the following goals: The choice of methods of dilatometric and viscometric studies. Investigation of the thermophysical properties of a group of phosphate glasses. Analysis of the obtained dependencies in order to obtain conclusions about the structure of the studied glasses. To measure the average temperature coefficient of linear expansion in the temperature range of 20Ã·300â, the softening temperature, the glass transition temperature, the temperature coefficient of linear expansion above and below the glass transition transition interval, the dependence of the viscosity change on the temperature, an industrial dilatometer DKV-5A, a dilatometer of the V.P. Klyuev system, and a simplified VKU viscometer were used. The analysis of the obtained results was carried out using the free volume theory and the Gibbs â Di Marzio theory. As a result, the obtained dependences were described, and a number of conclusions were made about the structure of phosphate glasses. The validity of the use of theories for the analysis of the studied thermophysical properties is confirmed.
