Characteristics of zone melted germanium ingots
Technically, germanium is classified as a metalloid or semimetal. One of a group of elements that have both metallic and nonmetallic properties.In metallic form, germanium is silvery, hard, and brittle.
Germanium's unique properties include transparency to near-infrared electromagnetic radiation (wavelengths between 1600-1800 nanometers), high refractive index, and low optical dispersion.
Metalloids are also essentially semiconductors.The Zone melted germanium ingot can be further grown into crystals and then sliced for use in semiconductors and optical lenses.
Like most rare metals, germanium is produced as a by-product of base metal refining and is not mined as a primary material.Germanium is most commonly extracted from sphalerite, but can also be extracted from fly ash coal (produced by coal-fired power plants) and some copper ores.

Product Application
Zone melted germanium ingot
Applications of zone smelted germanium ingots in various fields
Germanium is an important semiconductor material with extensive and important applications in semiconductors, aerospace measurement and control, nuclear physics detection, optical fiber communications, infrared optics, solar cells, chemical catalysts, biomedicine and other fields.
Germanium crystals grow and form lenses and windows used in infrared or thermal imaging optical systems. About half of all such systems, which rely heavily on military requirements, contain germanium.
Germanium tetrachloride is used as a dopant or additive to increase the refractive index of the quartz glass core of fiber optic lines. By incorporating germanium, signal loss can be prevented.
The germanium substrate forms one layer in a multi-layer system that also uses gallium, indium phosphide and gallium arsenide. Such systems, known as concentrated photovoltaics (CPV) because they use concentrating lenses to amplify sunlight before it is converted into energy, are highly efficient but more expensive to manufacture than crystalline silicon or copper-indium-gallium . diselenide (CIGS) cells.
Other uses of germanium in electronics include in-phase memory chips (which are replacing flash memory in many electronic devices due to their energy-saving advantages) and substrates used in the production of LEDs.Various forms of germanium are also used in the production of base materials for PVC for space-based (satellite) and ground-based power generation.
Packing Delivery
Packaging (select packaging method according to product characteristics):
1. Bag (double-layer vacuum & double-layer inert gas protection)
2. Bottled (double-layer vacuum & double-layer inert gas protection)
Packaging (can be customized according to customer needs)
1. xx g/bag & xx Kg/bag
2. xx g/bottle & xx Kg/bottle
It should be stored in a cool, ventilated, dry, clean and chemical-free warehouse. Moisture proof. Do not store or transport together with acid or alkali products. During transportation, it must be protected from rain and shock. Be careful when loading and unloading to prevent collision and rolling and prevent mechanical damage.
