Lead metagermante is one of the germanates of lead with the chemical formula of PbGeO3. Other germanates include Pb5Ge3O11.[1]
Preparation
Lead metagermanate can be obtained by the reaction of germanium dioxide and lead acetate.[2]
Properties
Lead metagermanate is a solid with a strong thermoelectric effect.[3] It has two structural forms: the trigonal and the orthorhombic, with a transition temperature above 600 °C.[4][5] Under high pressure, lead metagermanate can also form cubic crystals.[6]
