General description

Gallium is a rareearth element that is widely used in smart electronic devices and integratedcircuits as it provides the advantages of low energy consumption and highcomputational speeds. Due to its high boiling point and low melting point, itexhibits a wide temperature range in the liquid state. It tends to formsulfate, chloride, and phosphate complexes due to its high charge. Thecompounds of gallium find applications in advanced semiconductors and LEDchips.

Application

Gallium can be used as a precursor to synthesize:
  • Gallium nitride and other Ga-based compounds for optoelectronic applications.
  • Sulfur/gallium hybrid cathode material for lithium-sulfur batteries. The surface of Ga metal promotes the redox reaction of lithium polysulfides due to its electrocatalytic effect.
  • Ga-based liquid alloys for the fabrication offlexible electronic devices.

Features and Benefits

  • Excellent conductor of heat and electricity
  • Wide temperature range in the liquid state
  • Lowvapor pressure at high temperature
