Nowadays
Gallium has a unique property located in a liquid state at a temperature at 30 to 2230 degrees Celsius. In this regard, it is used in the manufacture of thermometers. And now the most common up to 1200 degrees. It is used in signaling devices composed of indium. This alloy melts at a temperature of 16 degrees and is the most l fusible alloys. Adding gallium in the glass it can be obtained from the high refrangibility, but if you add gallium oxide, the glass is good passes infrared light. Even aware of the use of gallium in dentistry, where it is used stamps.
