Gallium, atomic no.: 31, symbol as Ga, weight at 69.723, ?is the only metal, except for mercury, caesium, and rubidium, which can be liquid near room temperatures; this makes possible its use in high-temperature thermometers. It has one of the longest liquid ranges of any metal and has a low vapour pressure even at high temperatures.
Ultra-pure gallium has a beautiful, silvery appearance, and the solid metal exhibits a conchoidal fracture similar to glass. The metal expands on solidifying; therefore, it should not be stored in glass or metal containers, as they may break as the metal solidifies.
High-purity gallium is attacked only slowly by mineral acids. Gallium arsenide is capable of converting electricity directly into coherent light and gallium arsenide is a key component of LEDs (light emitting diodes). In the 1990s gallium nitride (GaN) was discovered to emit blue light in light-emitting diodes (LEDs). As red and green LEDs were already known, this meant that red green, and blue LEDS could be used in full-colour LED displays while white LEDs and blue laser devices became possible as well.

Standard Specifications
Gallium Metal is the primary raw material for making semi-conductor materials such as gallium arsenide, gallium phosphide, gallium antimonide. It can also be mixed with elements like germanium and silicon for producing semi-conductor, or used to make gallium oxide, gadolinium-gallium garnet as storage and memory components.
