摘要：

Alkali phosphate, phosphate-silicate, and phosphate-germanate glasses were studied by means of high-temperature acoustics and Rayleigh-Mandelstam-Brillouin (RMBS) and Raman scattering (RS) spectroscopies. Temperature-temporal dependences of the ultrasound velocity in the glass melts were measured at temperatures up to 1550 degrees C. From the RMBS spectra the Landau-Placzek ratio and frequency shifts were found. A theory of the fluctuations freezing at the cooling of the glass melt was applied to separate the contributions of the frozen-in density and concentration fluctuations to the Rayleigh scattering losses. A comparison was drawn with the losses in silica glass. The RS spectra allowed the identification of the constant-stoichiometry groups. The feasibility of the system xNa(2)O-(40 - x)K2O-30Al(2)O(3)-30P(2)O(5) for the fabrication of low-scattering glasses was ascertained.
