What is Germanium powder? Germanium powderis a material of strategic significance and has a wide range of applications in high-tech fields. This article will detail the properties of germanium powder, the preparation of germanium powder, and the application of germanium powder to help readers understand the importance and application value of germanium powder. Properties of germanium powder. Germanium powder is a gray crystal belonging to the tetragonal crystal system, with lattice constants a=0.564nm and c=0.590nm. Germanium powder has a 5.3g/cm density and a melting point of 1026°C. The hardness of germanium powder is low, 3~3.5 on the Mohs scale. Germanium powder has a metallic luster and is easily oxidized in the air, forming an oxide film on the surface. Germanium powder has good electrical conductivity, thermal conductivity, flexibility, and reflective properties. The preparation methods of germanium powder mainly include the chemical reduction method, vacuum distillation method, electrolytic reduction method, and so on. Among them, the chemical reduction method is the most commonly used. The chemical reduction method uses germanium oxide and a reducing agent to conduct a reduction reaction to reduce germanium into germanium powder. Common reducing agents are carbon, carbon monoxide, hydrogen, etc. Carbon is the most commonly used reducing agent, and the reaction temperature is 800~1000°C. The vacuum distillation method utilizes the difference in vapor pressure between germanium and other substances, evaporates at high temperatures, and condenses it into germanium powder. The purity of vacuum distillation is high, but the yield is low. The electrolytic reduction method uses the ion reaction in the electrolyte to reduce germanium into germanium powder. The purity of the electrolytic reduction method is higher, but the energy consumption is higher.
Application of germanium powder Germanium powder is widely used in high-tech fields, mainly including the following aspects: Germanium powder is one of the important materials for manufacturing semiconductor devices and can be used to manufacture germanium transistors, germanium diodes, germanium rectifiers, etc. Especially in the fields of high-frequency devices, microwave devices, and optoelectronic devices, germanium powder plays an important role. Germanium powder is one of the important materials for manufacturing infrared detectors, which can be used to manufacture mid-wave infrared detectors, short-wave infrared detectors, hyperspectral infrared detectors, etc. Germanium powder has better-infrared response performance, a high detection rate, and stability. Germanium powder is one of the important materials for electron microscopes, which can be used to manufacture transmission electron microscopes, scanning electron microscopes, etc. The lattice constant of germanium powder is similar to that of silicon, and it has good electrical conductivity, thermal conductivity, and flexibility. It is one of the ideal materials for electron microscopes. Germanium powder is one of the important materials for manufacturing solar cells and can be used to manufacture single-crystal germanium solar cells, polycrystalline germanium solar cells, etc. Germanium batteries have higher efficiency and good stability, but the cost is higher.
Other aspects of germanium powder In addition to the above application fields, germanium powder can be used to manufacture optical fiber communications, lasers, magnetic materials, superconducting materials, and other fields. In a word, germanium powder is important and has wide application prospects in the high-tech field. With the continuous development and progress of science and technology, the application fields of germanium powder will continue to expand and improve.
