Germanium block recovery_ Germanium ingot recycling price_ Precious metal recycling and refining manufacturers

Germanium blocks, also known as germanium ingots, are commonly used as raw materials for the production of germanium single crystals and for purifying germanium. Germanium ingots generally refer to zone melting germanium ingots. Zone refined germanium ingots refer to germanium ingots obtained by zone melting method. Qualified products have a purity of over 99.9999%, a resistivity of over 47 ohm. cm (23+/-0.5 degrees), a strip-shaped, trapezoidal cross-section (26mmB21mm T23mmL), a silver gray metallic luster, no surface cracks (polycrystalline patterns on closer inspection), no sticking slag, brittleness, easy fracture, hardness of about 5.0, and micro conductivity, It belongs to typical semiconductors and is insoluble in hydrochloric acid, nitric acid, and alkali, but soluble in HF, aqua regia, and hot NAOH solutions. The dissolution rate is faster in the presence of H202. Zone melting germanium ingots are polycrystalline materials with high purity, mainly used as raw materials for the production of germanium single crystals. China is the world's leading producer of germanium materials, with an annual output of over 60 tons. Due to its main use in the manufacturing of satellite batteries and night vision devices in weapons and equipment, and its extremely scarce content on Earth (according to the current domestic development rate of germanium, it will be consumed in about 50 years), developed countries store and release it as a strategic reserve material. Waste germanium blocks are one of the sources of germanium waste recycling, including germanium sheet recycling, industrial germanium recycling, germanium particle recycling, single crystal germanium recycling, germanium stone recycling, and germanium rod recycling.
