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]
