Germanium The Role Of The Human Body

Sep 26, 2017

Germanium is important semiconductor materials, in the semiconductor, aerospace measurement and control, nuclear detection, optical fiber communication, infrared optics, solar cells, chemical catalyst, biomedical and other fields have extensive and important applications. According to the U.S. geological survey data (2015), the proportion of global germanium end users is as follows: fiber fiber 30%; Infrared fiber 20%; Polymerization catalyst 20%; Electronic and solar components 15% and other (phosphor, metallurgy, and chemotherapy) 15%. Germanium, tin and lead are the same group in the periodic table of the elements, which were discovered and utilized by the ancient people, and the germanium has not been mined by the industry since long ago. This is not because germanium is less abundant in the earth's crust, but because it is one of the most dispersed elements in the earth's crust

Germanium is widely distributed in nature. Copper, iron ore, sulphide mines and rocks, soil and springs contain trace amounts of germanium. The content of germanium in the crust is seven parts per million, which is less than the common elements such as oxygen and silicon. However, it is more than arsenic, uranium, mercury, iodine, silver and gold. Germanium, however, is so dispersed that there is almost no concentration of germanium, so it is known as the "sparse metal". The discovered germanium deposit (including germanium 5 ~ 7%), germanium (10 % of germanium) and germanium sulfide (7 %). Germanium ore has two kinds of germanium content: 200ppm and 393ppm, and the color is grey and red.

Storage transport

Store in cool, ventilated, dry, clean, non-chemical corrosive atmosphere. Moisture proof. Do not mix with acid and alkali products. In the transportation process should be rain-proof, shockproof. Handle with care when loading and unloading, prevent collision and roll, prevent mechanical damage.

Toxicology data

It is generally believed that germanium is not important to the health of plants and animals. However, some of its compounds can harm human health. For example, germanium tetrachloride and methylgermanium, which are liquid and gases, can cause great irritation to the eyes, skin, lungs and throat. Since germanium is a rare element in the mineral and carbonaceous material, and the amount used in commercial applications is not much, it has no effect on nature.

Germanium is a low toxicity, poisoning animals after a large number of metal germanium and germanium oxide absorption can cause pulmonary inflammatory damage, inhalation of germanium tetrachloride and tetrafluoride germanium has strong stimulation to the respiratory tract mucous membrane, germanium tetrachloride can also cause kidney damage, germanium hydrogen, including germanium methane (GeH4), germanium oxide (Ge2H6) and germanium oxide (Ge3H8) have similar hydrogen arsenide, antimonide hydrogen hemolytic effect.

The role of the human body

Activation of biological electric current, promote blood circulation, improve and prevent the discomfort of the body, protect the red blood cells, resist radiation outside attacks and make it intact metabolism and immunity to restore and improve the body's natural healing power. Anti-tumor, anti-inflammatory, antiviral, and germanium metal can be seen by a small amount of energy (temperature) can play a role, this feature can make it through contact with human body health
