The Technology-Critical Semiconductor Metal

Powering next-generation connectivity and optoelectronics with Less Common Metals.

Gallium is the element lighting up the digital world. While Silicon built the first era of computing, Gallium is building the future of high-speed connectivity and brilliant displays. From the laser reading your data to the 5G network connecting your phone, Gallium operates where traditional semiconductors reach their physical limits.

As a specialist UK manufacturer of advanced materials, Less Common Metals (LCM) understands the exacting demands of the electronics and medical sectors. Located in Ellesmere Port, UK, we supply the exceptionally high-purity Gallium required to keep global communication and technology moving at the speed of light.

What is Gallium?

Gallium is a soft, silvery-blue metal that is famous for its unusually low melting point at just 29.7°C (85.5°F). 

Fun fact: A solid piece of Gallium will actually melt in the palm of your hand!

Though it doesn’t occur as a free element in nature, it is extracted as a byproduct of smelting Aluminium and Zinc. Today, it is universally recognised by global governments as a “Technology-Critical Element.”

What is Gallium used for?

Gallium is predominantly consumed by the advanced electronics industry, where its unique semiconductor properties are unparalleled in:

  • High-Speed Electronics & 5G: When combined with arsenic to create Gallium Arsenide (GaAs), it produces a semiconductor that operates at much higher frequencies than silicon. This makes it indispensable for microwave circuits, high-speed switching circuits, and the radio frequency (RF) amplifiers that power modern smartphones and 5G cellular networks.

  • Optoelectronics (LEDs & Lasers): Gallium is the reason we have bright, energy-efficient lighting. Compounds like Gallium Nitride (GaN) are the foundational materials used to manufacture brilliant white and blue Light-Emitting Diodes (LEDs), as well as the diode lasers used in medical equipment and fibre-optic communications.

  • Medical & Pharmaceuticals: Gallium has unique biological properties. It is used in pharmaceuticals to treat certain inflammatory diseases, and specific radioactive isotopes (like Gallium-68) are critical radiopharmaceuticals used in PET scans to detect and image tumours.

  • Specialty Jewellery: In niche applications, Gallium is sometimes alloyed to produce artificial jewellery. This is all thanks to its brilliant, mirror-like finish when solid.

Gallium Industry Insight

The Gallium Nitride (GaN) Revolution

The tech world is currently undergoing the “GaN Revolution.” Silicon power chargers and transistors are reaching their physical limitations in terms of size and heat generation. Gallium Nitride (GaN) components can conduct electrons more than 1,000 times more efficiently than Silicon. Thus, allowing for power adapters and EV chargers that are dramatically smaller, faster and cooler. As this technology scales, the strategic importance of securing high-purity Gallium continues to rise exponentially.
