Abstract

The invention relates to the chemical production of glass, more precisely to the working out operational modes for producing a charge mixture for synthesising phosphate glass in large-volume production. The inventive method consists in preparing a glass batch based on ortho-phosphoric acid, metallic oxides and salts, boiling said batch and producing a glass melt. The preparation of said glass batch is carried out in three following stages: in the first stage, a phosphate pulp based on ortho-phosphoric acid and the oxides of elements of groups 3 to 5 of the Periodical system and/or an alkaline-earth salt, and an alkaline suspension based on the solution of alkali and alkaline-earth salts and/or the salts of transition alloying metals are separately produced. In the second stage, the phosphate pulp is neutralised with the aid of an alkaline suspension by mixing said solutions. The third stage consists in drying the neutralised solution of the pulp and calcinating the batch until chemical interactions are completed, the subsequent boiling of the thus obtained dry batch being carried out until a homogenous melt is obtained at a temperature ranging from 800 to 1250 °C.
