2. Application:
Germanium Application:
Jewelry categories: necklaces, bracelets, pendants, watches and so on ......
Wear: underwear, belts, brooches, glasses, insoles, etc. ...
Technology: smart bracelet, smart watches, health detectors, etc. ... ...
Beauty categories: facial massage equipment, beauty stick, slimming equipment, etc. ... ...
3.Germanium, arare precious metals, smelting and refining requirements are quite strict, the quality of amaterial
of germanium is very hard, is widely used in aerospace measurement and control, nuclear detection, optical fiber
communication, infrared optics, biomedical and other fields. Because of its high value and the practical medical
value of itself, is also used in facial massage stick, knee pads, wristbands, waist support, soreness and hot
product, sell well throughout southeast Asia, especially in recent years in South Korea, Japan sparked a buying
frenzy enduring.
4. Packing:
