    Rare Metals Pure Germanium Granules 99.999% 5N Ge Ingot Germanium Pellet

    pure germanium granules 99.999% 5N with factory price


    1. Lustrous, hard, grayish-white solid metalloid in the carbon group, chemically similar to its group neighbors tin and silicon.

    2. Purified germanium is a 'p-type' semiconductor material.

    3. Conductivity depends largely on added impurities.

    4. Attacked by nitric acid and aqua regia, but stable in water, acids, and alkalies in absence of dissolved oxygen, low toxicity.

    Germanium are commonly used as a semiconductor material for transistors. The first generation of semiconductors were based solely on germanium.

    However, most of today’s semiconductor production is based on silicon and germanium that widely applied in semiconductor, aerospace control, nuclear physics, optical fiber communication, infrared optics, solar cells, chemical catalyst, biomedical and other fields.


    Germanium granules generally will be vacuum packed in 1kg/bag or bottle to prevents oxidation and keeps your elements shine forever. Also could be packed according to customer request.
