Abstract

The phase composition of xerogel powders of the CaO–ZrO2–Nb2O5–SiO2 system after heat treatment at 1273 K with different Nb2O5 content was established. The temperatures of the physical and chemical processes occurring during the powders heating were determined. It was found that the complete replacement of ZrO2 by Nb2O5 resulted in the formation of niobium-containing phases with a change in the structure of the powders.
