This 99.9999% (6N) 'element collection quality' gallium is the highest purity product readily available to the general public at an affordable price. It is sold in a crystal clear screw cap plastic bottle so you can look at the pure gallium beads. For your convenience you can easily pour out just the amount of gallium you want to work with, rather than having to melt a large solid lump of metal. We advise you do not handle with your hands directly. Firstly, as it covers your hands in a fine grey covering that is difficult to remove. Secondly it will contaminate the pure gallium. Use Nitrile gloves or a clean plastic spatula or spoon. History: First proposed to exist by Dmitri Mendeleyev in 1871 based on gaps in his newly created Periodic Table of Elements, gallium was discovered and obtained by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875. Elemental gallium does not occur in free form in nature but trace amounts of gallium are found in zinc ores and bauxite as well as in the by products of burning coal. Properties and uses: Elemental gallium is a soft, silvery metal, it is a brittle solid at low temperatures, Gallium melts near room temperature at 29.76ºC and has one of the largest liquid ranges of any metal, so it has found use in high temperature thermometers. Gallium easily forms alloys with most metals and has been used to create low melting alloys. Gallium is used as a doping material for semiconductors and has been used to produce solid-state items like transistors and light emitting diodes. Gallium arsenide (GaAs) can produce laser light directly from electricity. Large amounts of gallium trichloride (GaCl3) have been gathered to build the Gallium Neutrino Observatory, an observatory located in Italy built to study particles called neutrinos which are produced inside the sun during the process of nuclear fusion.
