What is the normal phase of gallium?

The normal phase of the element Gallium is solid. This silvery-blue metal has a melting point of 29.76 degrees Celsius or 302.91 Kelvin and a boiling point of 2200 degree Celsius or 2473 Kelvin. Therefore, it remains a solid substance at average room temperature.

Dmitri Mendeleyev predicted the presence of Gallium in the periodic table and termed it "aka-aluminum" in 1871. In 1875, Gallium was officially discovered by Paul-Émile Lecoq de Boisbaudran by spectroscopic method. Gallium is not available in the nature in pure form. Its traces can be found in coal and a few other elements. Gallium is highly reputed for the production of semi-conductors.
