Germanium, with the chemical symbol Ge, is an important non-metallic element with unique physical and chemical properties. Germanium crystals, especially polycrystalline germanium, are widely used in many fields due to their low thermal conductivity, low electrical resistivity, high mechanical strength, and high crystallinity.

1、 Semiconductor field

As an excellent semiconductor material, germanium crystals play an important role in fields such as integrated circuits, optoelectronic devices, and solar cells. Transistors, photodiodes, and other devices manufactured using germanium crystals not only have stable performance but also high efficiency. In addition, with the global semiconductor industry shifting to mainland China, the demand for germanium crystals in manufacturing semiconductor power devices is also constantly increasing, and their market prospects are very broad.

2、 Optical field

Due to its excellent infrared transmission performance, germanium is widely used in infrared optical systems, such as infrared lenses, infrared filters, and infrared windows. These applications make germanium crystals play an irreplaceable role in infrared detection, night vision devices, thermal imaging, and other fields.

3、 Medical field

Germanium based drugs are commonly used to treat neurological diseases, arthritis, and osteoporosis, and have good therapeutic effects. With the continuous development of medical technology, the application prospects of germanium crystals in the medical field will also be broader.

4、 Nuclear industry, consumer electronics, and other fields

Germanium can be used to prepare high-purity germanium-76, which plays an important role in fields such as detectors and nuclear fuel rods. Meanwhile, with the continuous expansion of the consumer electronics market, germanium crystals also play an important role in the manufacturing of devices such as smartphones and tablets.
