SIMA OFFERS

  • SIMA carries 3N-6N type material. 

GENERAL INFO

  • Elemental gallium does not occur in nature, but as the gallium (III) salt in trace amounts in bauxite and zinc ores.
  • A soft silvery metallic poor metal, elemental gallium is a brittle solid at low temperatures. 
  • Its melting point is used as a temperature reference point. �
  • Prior to the semiconductor era, its primary uses were in high-temperature thermometric applications and in preparation of metal alloys with unusual properties of stability, or ease of melting.

APPLICATIONS IN METALLURGY

Semiconductors

  • The semiconductor applications are the main reason for the low-cost commercial availability of the extremely high-purity (99.9999 +%) metal. 
  • About 66% of semiconductor gallium is used in the U.S. in integrated circuits (mostly gallium arsenide), such as the manufacture of ultra-high speed logic chips and MESFETs for low-noise microwave preamplifiers in cell phones. 
  • About 20% is used in optoelectronics. Worldwide gallium arsenide makes up 95% of the annual global gallium consumption.
  • Aluminium gallium arsenide (AlGaAs) is used in high-powered infrared laser diodes.
