Synthesis of Lead-Containing Glass Crystalline Materials with Various Crystallization Nucleators

Ce-, Nd-, and Er-containing glasses based on the PbO–SiO₂ binary system are synthesized. The process of mass crystallization for the production of glass-crystalline (ceramic glass) materials as a result of their heat treatment at different temperatures is studied. Compositions of glass ceramics with the indicated crystallization nucleators are developed. It is established that a glass-crystalline material with improved physicochemical properties has been synthesized at relatively low crystallization temperatures (750°C).
