Abstract— An analysis of the properties of lead metasilicate powders synthesized by the microwave method and low-melting (900°C) glass obtained based on it has been conducted. Physical and chemical studies have shown that the synthesized lead metasilicate and the glass obtained from it are promising materials for use in various fields, namely as a wide-bandgap semiconductor, photocatalyst, and glass used for protection against ionizing radiation.

Keywords: hydrothermal-microwave synthesis, lead silicate, XRD, transmission, absorption, gamma-irradiation
