Gallium
Chemical symbol: Ga
Specific gravity: 5.91 g/cm3
Colour: polished silver
Melting temperature: 29.76?C
Gallium is a rare metal, very fragile and with a very low melting temperature, so it can also liquefy simply due to environmental exposure and if held in the hands. Because of its extreme delicacy, it tends to fracture in a very similar way to glass.
Although its melting temperature is very low, conversely its boiling temperature is particularly high, in fact it is around 2403?C. Applications of gallium
In thermometers for high temperatures due to its peculiarities and as a substitute for mercury as it tends to remain liquid even when lower than its melting point

Optoelectronic devices (LEDs and OLEDs)
Solar power plants
Permanent magnets for electric vehicles
Semiconductors
Electronic components
Additive for metal alloys
Smartphones, tablets and PC
