Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person's hands at normal human body temperature of 37.0 °C (98.6 °F). Gallium is predominantly used in electronics.
Gallium, chemical element of Group 13 (the boron group) of the periodic table. It liquefies just above room temperature. Gallium compounds, some of which form the basis for light-emitting diodes (LEDs), have valuable semiconductor and optoelectronic properties.
Element Gallium (Ga), Group 13, Atomic Number 31, p-block, Mass 69.723. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
The liquid state of gallium makes it easy to break into particles for making colloids and soft composites that have unusual properties due to the deformable nature of the filler. This review summarizes the truly unique and exciting properties of gallium liquid metals.
By harnessing the unusual properties of a liquid metal called gallium, materials scientists aim to create a new generation of flexible devices for virtual reality interfaces, medical monitors,...
At a ratio of less than 0.0001 parts platinum to one part gallium, this new liquid metal alloy is 1,000 times more efficient than a solid-state catalyst with around 10% platinum. The liquidity of the gallium-platinum alloy offers yet one more advantage – it is self-cleaning, much like a water fountain, which adds to its efficiency and longevity.
Gallium‐based liquid metals combine metallic and fluidic properties at room temperature. Unlike mercury, which is toxic and has a finite vapor pressure, gallium possesses low toxicity and effectively zero vapor pressure at room temperature, which makes it amenable to many applications.
Liquid metal gallium has been widely used in numerous fields, from nuclear engineering, catalysts, and energy storage to electronics owing to its remarkable thermal and electrical properties along with low viscosity and nontoxicity.
Gallium-based liquid metals have gained plenty of attention in the scientific community due to their extraordinary properties. The most intriguing properties of liquid metals are high surface tension, density anomaly, high electrical and thermal conductivity, phase transition, and their temperature and low viscosity in combination with their ...
A shell-like surface oxide layer forms on liquid Ga when it comes in contact with air, which allows three-dimensional liquid structures to hold their shapes. Researchers can exploit that feature to create microfluidic channels with almost arbitrary geometries, such as the spiral shown in this video.
