The element so instrumental in the success of CIGS or Copper Indium Gallium Selenide solar panels garners little respect. If you do some research on Gallium you will see very few articles on this element. What you see is people talking about how to make melting spoons, and talk of the metal melting in your hand due to its low melting point of 85° F or 29.8° C. Here we are going to go over the history of Gallium and its uses in technology today.

Gallium has the symbol of Ga and the atomic number 31 on the periodic table of the elements. In 1875 Paul Emile Lecoq de Boisbaudran discovered Gallium spectroscopically. He saw Gallium´s characteristic two violet lines. Gallium does not occur free in nature. Lecoq was able to obtain the free element using electrolysis.

Gallium is found in bauxite, sphalerite and coal. It is primarily extracted from Aluminum and Zinc production. The exact amounts mined and recycled are very difficult to quantify. According to the United States Geological Survey the total amount mined in 2010 was approximately 106 t and the total recycled was approximately 78 t. Gallium supply is highly reliant on other Aluminum and Zinc mining for its supply, when the prices of the base metals fall the amount of Gallium available will be highly affected. Similar to other rare industrial metals, mining companies will not invest in the production of these metals because the markets are so small.

The uses of Gallium are found all around you. Semiconductors, LED´s, medicine, electronic components, CIGS solar and new tech like IGZO (Indium, Gallium, Zinc and Oxygen) LCD screens. The new iPhone 5 will have this kind of LCD. Over 90% is used in electronic components in the form GaAs (Gallium Arsenide). Recently CIGS solar panels reached an unprecedented 20.3% efficiency once again proving that CIGS is the most efficient form of solar on the market. The technology that will greatly increase the use of Gallium is smartphones. Analysts predict that smartphone use will grow at a rate of 15-25% over the next several years. Recently LED´s backlit screen TV´s and computer monitors have been all the rage. The LED screen market will continue to grow, further putting strain on the small Gallium supply.

The top producers of Gallium are China, Kazakhstan and Germany. Once again China has a strong position in the production of a rare industrial metal. The difference with Gallium is that almost 40% of the metal produced every year is coming from recycling.

With all of the new technologies coming along using Gallium what will the market for this metal look like in a few years? Unlike some metals like Silver and Gold, Gallium is not traded on the LME (London Metal Exchange). This makes the price of Gallium very stable. Rare industrial or technical metals are small markets with big possibilities. So if you are looking for an investment that is rarely talked about, Gallium could be a good option.
