Germanium Powder 5N Ge Powder CAS 7440-56-4

Item No.: Tr-Ge
Germanium is a light gray metal. According to X-ray studies, the atomic arrangement in germanium crystals is similar to diamond. Structure determines performance, so germanium is as hard and brittle as diamond.
Purity: 99.999%
Particle Size: 100 mesh
Germanium Powder Properties

About Germanium Powder 5N Ge Powder:

Germanium is a silver-gray crystal. Germanium's melting point is 937.4°C, and Germanium's boiling point is 2830°C. Germanium's chemical formula is Ge, which can be used to manufacture semiconductor materials. Germanium is a chemical element, element symbol Ge, atomic number 32, atomic weight 72.64, in the fourth period of the chemical periodic table, the IVA group. Elemental Germanium is a kind of grey metal, shiny, qualitative hard, belongs to the carbon group, has chemical properties and kin tin similar to silicon, is insoluble in water, hydrochloric acid, dilute caustic solution, soluble in aqua regia, concentrated nitric acid or sulfuric acid, with both sexes, therefore, soluble in molten alkali, alkaline peroxide, alkali metal nitrate or carbonate, relatively stable in the air.

Ge germanium is widely distributed in nature. Traces of Germanium are found in copper, iron, and sulfide ores, as well as in rocks, soil, and springs. Germanium is found in the earth's crust at seven parts per million, less than common elements such as oxygen and silicon but more than arsenic, uranium, mercury, iodine, silver, and gold. Germanium, however, is so dispersed that there is hardly any concentrated Germanium ore that it is known as a "dispersed metal."

How is Germanium Powder 5N Ge Powder Produced? 

The extraction method of germanium is to first chlorinate the germanium enrichment with concentrated hydrochloric acid to produce germanium tetrachloride, then remove the main impurity arsenic with hydrochloric acid solvent extraction method, and then purify it by two rectification of quartz tower, and then wash it with high purity hydrochloric acid to obtain high purity germanium tetrachloride, and germanium tetrachloride with high purity water to obtain high purity germanium dioxide. Some impurities will enter the hydrolysis mother liquor, so hydrolysis is also a purification process. After drying and calcining, pure germanium dioxide is reduced with hydrogen in the quartz tube of the reduction furnace at 650-680℃ to obtain metallic germanium. High-purity germanium (impurities less than 1/1010) used in the semiconductor industry can be obtained by zonal smelting.


Use of Germanium Powder 5N Ge Powder:

Germanium has many special properties in semiconductor, aerospace measurement and control, nuclear physics detection, optical fiber communication, infrared optics, solar cells, chemical catalysts, biomedicine, and other fields with a wide range of important applications, an important strategic resource. In the electronics industry, alloy pretreatment in the optical industry can also be used as a catalyst.

High-purity germanium is a semiconductor material. It can be extracted from high-purity germanium oxide by reduction and smelting. The single crystal of germanium mixed with a small number of specific impurities can be used to make various transistors, rectifiers, and other devices. Compounds of germanium manufacture fluorescent plates and various kinds of high-refractive glass.

Germanium single crystal can be used as a transistor, the first generation of transistor material. Germanium is used in radiation detectors and thermoelectric materials. High-purity germanium single crystal has a high refraction coefficient, transparent to infrared light, not through visible light and ultraviolet light. It can be used as a germanium window, prism, or lens for infrared light penetration.

The annual demand for germanium in the field of infrared optics accounts for 20-30% of germanium consumption. The germanium infrared optical devices are mainly used as optical materials for lenses, prisms, windows, filters, and so on in the infrared optical system.

Germanium used in solar cells accounts for 15% of total germanium consumption. The future demand growth of germanium series products in the solar cell field is mainly reflected in two aspects: the rapid development of the aerospace field and satellite market and the growth of the ground photovoltaic industry.


Storage Condition of Germanium Powder 5N Ge Powder CAS 7440-56-4 :

The damp reunion will affect germanium powder dispersion performance and using effects. Therefore, Ge powder should be sealed in vacuum packing and stored in a cool and dry room. The germanium powder can not be exposed to air. In addition, the product should be avoided under stress.
