· K2PbO3

K2PbO3 is a lead potassium oxide ceramic compound belonging to the family of mixed-metal oxides. This material is primarily of research and specialized industrial interest, used in applications requiring lead-containing ceramics such as high-permittivity dielectrics, glass formulations, and ferroelectric components. Its notable characteristics include a relatively high density and potential applications in electronic ceramics, though it has largely been superseded in many traditional uses by lead-free alternatives due to environmental and toxicological concerns.
