Abstract: Powder X-ray diffraction spectra of potassium nitrate embedded into porous boron-silicate glasses have been obtained. The temperature range of spectra recording was 100 – 400 K. The phase ratio of samples at various temperatures and its relationship to temperature treatment and to the way of embedding material were analyzed.
