Note: according to user requirements of nano particle can provide different size products. Product performance 1. It can be made into dry powder, wet powder and dispersion liquid as required;2. Particle size and purity can be adjusted as required;3. Exclusive customized production with good customer feedback. Application direction 1. Optical fiberGermanium doped fiber has the advantages of large capacity, small optical loss, low dispersion, long transmission distance and no environmental interference. It is the only fiber that can be used in engineering and is the main part of optical communication network. In addition, GeCl4 is also used in high-speed optical fiber Web, links, optical fiber sensors, optical fiber guidance and optical fiber latching devices, which has developed rapidly in recent years. 2. Infrared opticsAs an infrared optical material, germanium nano powder has the advantages of high infrared refractive index, wide infrared transmission band range, small absorption coefficient, low dispersive power, easy processing, flash and corrosion, etc. Especially suitable for window, optical lens, prism and filter materials of thermal imager, infrared radar and other infrared optical devices in military industry and major civil use. 3. Polymerization catalyst Germanium dioxide (GeO2) is a catalyst for the production of Polyethylene terephthalate (PET), it has long fiber, the beverage and various containers of edible liquid made by it are non-toxic, transparent and have good air tightness. 4. Electronic solar components Germanium semiconductor devices are used as diodes, triode transistor and composite transistors, germanium semiconductor photoelectric devices can be used as sensor of photoelectricity, hall and piezoresistive effect, and as radiation detector for photoconductance effect, it's widely used in color TV, computer, telephone and high frequency equipments, germanium tube is especially suitable for high frequency and high power devices, and can work normally under intense radiation and -40℃. Thermoelectric generation of Ge-Si and Ge-Te can be used for power switch of aerospace, satellite and space station. Three sided solar cells that with germanium substrate have closed perotities to GaAs/GaAs batteries, the mechanical strength is higher and the area of a single battery is larger. In the space application environment, the radioresistance threshold is higher than that of silicon battery, and the performance degradation is low, its application cost is close to the same power silicon panels, it has been applied to various types of military satellites and some commercial satellites and has gradually become the main space power source. Nano silicon is one of the research hot spots of anode materials at present. However, at room temperature, nano germanium powder has higher electron conductivity and lithium ion diffusion rate than nano silicon, so nano germanium is a strong candidate for the cathode materials of high-power lithium ion batteries. No wonder germanium is a promising high-capacity anode material for lithium ion batteries, germanium nanoparticles can be encapsulated in flexible carbon nanofibers as self-supported electrodes for high performance lithium-ion batteries. Storage conditions This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation. | ||||||||||||||||||
