Аннотация:Oxochloride lead-silicate glass is a material that has demonstrated promising spectral and luminescent properties in the mid-IR range. However, working with such systems is associated with a number of difficulties, including pyrohydrolysis and volatilization of the halide components of the batch, the loss of which can reach up to 50% of the initial amount, which adversely affects the functional characteristics. That is why the optimization of the technique for the synthesis of oxochloride lead-silicate glasses is of current interest task.
