Organic germanium have extremely high medical value. According a neww study, we found it contains other 2 million other elements, and have many functions like dehydrogenation enrichment oxygen, strengthen the body’s immune system, regulating the body nerve and endocrine systems and supress lipid peroxidation.
1) Anti-tumor effect
Scientist have pay a more attention on organic germanium anti-tumor effect, at home and abroad because whether zoology experimental and clinical studies have already achieved significant results.Because of the effect, organic germanium have been widely applied to clinical. In recent years Japan, the United States, Sweden and other countries have found organic germanium is good to cancer of the stomach, lung, uterus, breast, prostate cancer and multiple myeloma.

Metal is not only an important raw material of industrial construction, but also have the benefits to human health. Germanium is one of them. Germanium is a suitable trace element that is applied as a dietary nutritional supplement. You may possibly not commonly hear about Germanium before but you will probably be hearing a significant about it in the long term. Health professionals and scientists have been performing tests and studies on Germanium for a long time and now have discovered that Germanium has some significant benefits when taken as a daily supplement. Listed below are the very best six health benefits which have been connected with Germanium:

Watch gallium metallic melt in the hand and beat like a heart.

Gallium is considered to be non-toxic.
Gallium is a silvery, glass-like, soft metallic. It sits close to the non-metals in the periodic table and its metallic properties aren’t as obviously metallic as most other metals. Strong gallium is brittle and is a poorer electrical conductor than lead.
The solid metallic fractures conchoidally. (Conchoidally means like a shell – the fractured surfaces are curved like a sea shell.)
Gallium has the largest liquid range of any element and is 1 of the few metals that is liquid near space temperature (m.pt. 29.76 oC, 85.6 oF ), melting in the hand.
The other metals with this property are cesium, francium and mercury.
Bromine is the only non-metallic element that is liquid at or around room-temperature.
Gallium liquid clings to or wets glass and similar surfaces.
Gallium also has the unusual property that (like water) it expands as it freezes.
Four other elements expand when they freeze; silicon, bismuth, antimonyand germanium
Low melting gallium alloys are used in some medical thermometers as non-toxic substitutes for mercury.
Gallium arsenide is employed in semiconductor production mainly for laser diodes, light-emitting diodes and solar panels.It is also utilized to produce brilliant mirrors.

|Structure: usually hexagonal close-packed (v.high pressure required to solidify helium)||Color: colorless|
Most individuals know what speaking following breathing helium sounds like. If you don’t, listen here. And what about sulfur hexafluoride?
At shut to absolute zero, helium becomes a superfluid. How will it behave?
Helium is not recognized to be toxic.
Helium is a light, odorless, colorless, inert, monatomic fuel.It can form diatomic molecules, but only weakly and at temperatures shut to absolute zero.
Helium has the lowest melting point of any component and its boiling point is shut to absolute zero.
Unlike any other element, helium does not solidify but remains a liquid down to absolute zero ( K) below ordinary pressures.
The voice of somebody who has inhaled helium temporarily sounds higher-pitched.
Helium is used for filling balloons (blimps) and for pressurizing liquid fuel rockets.
Mixtures of helium and oxygen are used as an artificial ‘air’ for divers and others working below pressure. Helium is utilized instead of the nitrogen in regular air due to the fact, right after a long dive, helium leaves the body quicker than nitrogen, allowing faster decompression.
Helium is employed as a gasoline shield in the vicinity of arc welding and in cryogenics, preventing, for example, any reaction of hot metal welds with oxygen. The gas is employed in the semi-condictor business to provide an inert atmosphere for growing silicon and germanium crystals.It is also utilized as a higher temperature gas in titanium and zirconium production, and as a carrier gasoline in in fuel chromatography.
By virtue of its extremely low temperature, liquid helium is used to produce superconductivity in some ordinary metals.

A single measure of measurement is the component-element distance within the aspect. The bond length in GeGe is: 245. pm. It is not always easy to make sensible comparisons between the elements nonetheless as some bonds are quite quick simply because of multiple bonding (for instance the O=O distance in O2 is quick because of the the double bond connecting the two atoms.

|Structure: tetragonal, distorted fcc structure||Color: silvery-white|
|Harmful effects: Indium is considered to be of low toxicity.||Hardness: 1.2 mohs|
|Characteristics: Indium is a very soft, silvery-white lustrous metal. Indium liquid clings to or wets glass and similar surfaces. Like gallium, indium remains in a liquid state over a wide range of temperatures.When heated above its melting point, it burns with a violet flame to the sesquioxide (In2Othree).|
|Uses:Indium is utilized in the production of low-melting alloys, normally with gallium.The melting point depends on the ratio of indium to gallium.An alloy with 24% indium and 76% gallium, for example, melts at 16 oC. (1)This sort of alloy can be used as a non-toxic alternative to mercury in some applications.Compounds of indium are utilized in the semiconductor business for germanium transistors, thermistors, rectifiers and photocells.Indium can be coated on metals and evaporated onto glass, to form mirrors equal to that made with silver but more corrosion resistant.Indium-tin oxide thin films are employed for liquid crystal displays (LCDs).|

|Structure: rhombohedral; B12 is icosahedral.||Color: black|
|Hardness: 9.three mohs|
Boron compounds burn with a green flame. The distinctive colour leads to use in fireworks.
Boron is an ionic element – pure boron can exist as a mixture of positive and negative boron ions.
Elemental boron is not known to be toxic.
Boron is a metalloid, intermediate between metals and non-metals.It exists in several polymorphs (different crystal lattice structures), some much more metallic than others. Metallic boron is very hard and has a really high melting point.
Boron does not generally make ionic bonds, it forms stable covalent bonds.
Boron can transmit portions of infrared light.
Boron is a poor room temperature conductor of electricity but its conductivity improves markedly at higher temperatures.
Boron is employed to dope silicon and germanium semiconductors, modifying their electrical properties.
Boron oxide (B2O3) is employed in glassmaking and ceramics.
Borax (Na2BfourO7.10H2O) is used in making fiberglass, as a cleansing fluid, a water softener, insecticide, herbicide and disinfectant.
Boric acid (HthreeBO3) is used as a mild antiseptic and as a flame retardant.
Boron Nitride’shardness is second only to diamond, but it has much better thermal and chemical stability, hence boron nitride ceramics are employed in high-temperature equipment.
Boron nitride nanotubes can have a similar structure to carbon nanotubes. BN nanotubes are much more thermally and chemically stable than carbon nanotubes and, unlike carbon nanotubes, boron nitride nanotubes are electrical insulators.
Boron carbide (B4C) is employed in tank armor and bullet proof vests.
