99.999 High Pure Zone Refined Germanium Ingot for Sale
Description
Zone refined Germanium ingot is typically produced by upgrading germanium dioxide (GeO2) through an zone refining process. It involves passing the feedstock through a hot space, which produces a high purity molten metal. Impurities collect in the molten material and are pushed back as the germanium ingot solidifies on leaving the hot space.
