Product Overview
Germanium lumps are silver-white, brittle metallic materials known for their excellent semiconductor properties and outstanding optical performance. With a melting point of 937.4°C and a boiling point of 2830°C, they are chemically stable at room temperature and suitable for a wide range of industrial and scientific applications. Germanium is insoluble in water and dilute acids but dissolves in aqua regia, concentrated nitric acid, or sulfuric acid.
