High Purity Germanium Powder 5N Ge Powder CAS 7440-56-4, 99.999%

Description of Germanium Powder :

Germanium powder is usually grayish-white or light gray with a metallic luster. Depending on the specific preparation process, its shape can be spherical, cube, diamond, etc.. The density of germanium powder is about 5.3g/cm3. Porosity refers to the percentage of pores in the total volume of germanium powder, which will affect the hygroscopic property, electrical conductivity, and plasticity of germanium powder. Germanium powder has high stability to air, water, alkali, and other substances at room temperature. It is not easily oxidized or chemically reactive with these substances. Germanium powder has good plasticity and elasticity and can be transformed into products of different shapes and sizes. Germanium has special optical properties and high transmittance in the near-infrared region, so it is widely used in infrared optical components and optical fiber communication.

Application of  Germanium Powder :

Optical field: 

The application of germanium powder in optics is mainly as infrared optical components and optical fiber communication components. Because germanium has the advantages of high transmittance and low thermal expansion coefficient, germanium optical components have excellent optical properties and stability. In fiber optic communications, germanium powder is used to prepare key components such as fiber optic connectors and fiber optic attenuators, which can transmit optical signals at higher frequencies and over longer distances. 

Superalloy: 

Germanium powder can be used as one of the alloying elements in superalloys to improve the strength, corrosion resistance, and high-temperature stability of alloys. Especially in the aerospace field, and can be transformed into products of different shapes and sizes, rocket engines, and other high-temperature equipment. In addition, germanium alloys can be used to manufacture key components such as high-temperature bearings and gears. 

Catalyst preparation: 

Germanium powder can be used as a catalyst in petroleum cracking, ammonia synthesis, hydrogen production, and other industrial production. As catalyst carriers, germanium powder can improve the activity and selectivity of catalysts. In addition, germanium powder can also be used as an auxiliary agent of homogeneous catalysts to improve the stability and activity of catalysts. 

Electronics Industry: 

The application of germanium powder in the electronics industry is mainly an additive in semiconductor materials and electronic pastes. These slurries make electronic components such as transistors and integrated circuits. By adding germanium powder, the electrical conductivity and stability of electronic paste can be improved to ensure electronic components' manufacturing quality and reliability. In addition, germanium powder can be used as the main component of conductor paste to prepare thin film and hybrid integrated circuits. 

Medical field: 

Germanium powder has some special applications in the medical field. For example, germanium powder can be used for medical implants, such as artificial joints, dental plants, etc. Because germanium has good biocompatibility and corrosion resistance, It is possible to combine it with human tissues to lessen the risk of rejection and infection. In addition, germanium can also be used to prepare drug carriers and drug slow-release materials for treating major diseases such as tumors and cancers. 

Flame retardant: 

Germanium powder can be used as a flame retardant to prepare polymer materials. Adding germanium powder to polymer materials such as plastics and rubber can significantly improve its flame retardancy. In addition, germanium powder can be used as an additive to fire retardant coatings to improve the fire resistance of coatings. 

Luminous material: 

Germanium powder can be used as a luminescent material for display and other fields. For example, by combining germanium with compounds of other elements, luminous materials with different colors and durations can be prepared. These luminous materials are widely used in full-color displays, LED lighting, and other fields.


Production Method of Germanium Powder :

Physical law: 

The physical method is to prepare germanium powder from raw materials by mechanical grinding, grinding, and other physical means. The method mainly includes ball milling, crushing, grinding, etc. 

The ball milling method is to put germanium raw materials into the ball mill, add an appropriate amount of grinding media (such as zirconia, alumina, etc.), and grind at a certain speed for a certain time so that germanium raw materials are broken into fine particles. 

The crushing method is to put germanium raw materials into the crusher, add an appropriate amount of grinding media (such as diatomaceous earth, glass beads, etc.), and crush at a certain speed for a certain time so that germanium raw materials are broken into fine particles. 

The grinding method is to put the germanium raw material into the grinder, add the right amount of grinding agent (such as alumina, silicon carbide, etc.), and grind at a certain speed for a certain time so that the germanium raw material is ground into fine particles. 

Chemical method: 

The chemical method is the method of converting germanium raw material into germanium powder by chemical reaction. Commonly used chemical methods are electrolysis, hydrogen reduction, and REDOX method. 

The electrolysis method is the electrolysis of an aqueous solution containing germanium ion in an electrolytic cell so that germanium ion discharges on the cathode and forms germanium powder. The advantages of this method are high production efficiency, environmental pollution, and high production cost. 

The hydrogen reduction method uses hydrogen to reduce germanium oxide or germanium-containing raw materials under high temperatures and high pressure to produce germanium powder. The benefits of this method are lower production costs and less pollution to the environment, but safety needs to be paid attention to in the production process. 

The REDOX method produces germanium powder by reacting with germanium oxide or germanium-containing raw material with carbon or reducing agent at high temperatures. The benefits of this technique include lower production costs and less toxicity to the environment, but attention should be paid to controlling reaction conditions and purity.
