Liquid alloys containing mostly gallium and indium have been found to precipitate gaseous CO 2 into solid carbon and are being researched as potential methodologies for carbon capture and possibly carbon removal. [80] [81] Because gallium wets glass or porcelain, gallium can be used to create brilliant mirrors.
Galinstan is a brand name for an alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. [4] [5] In scientific literature, galinstan is also used to denote the eutectic alloy of gallium, indium, and tin, which melts at around +11 °C (52 °F). [5]
As of 2012, many mercury-in-glass thermometers are used in meteorology; however, they are becoming increasingly rare for other uses, as many countries banned them for medical use due to the toxicity of mercury. Some manufacturers use galinstan, a liquid alloy of gallium, indium, and tin, as a replacement for mercury.
A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes.
The liquid mercury wets the glass and thus provides for a vacuum tight seal. Liquid mercury was also used to seal the metal leads of early mercury arc lamps into the fused silica bulbs. A less toxic and more expensive alternative to mercury is gallium. Mercury and gallium seals can be used for vacuum-sealing rotary shafts.
The glass forming ability of gallium(III) sulfide and lanthanum sulfide was discovered in 1976 by Loireau-Lozac’h, Guittard, and Flahut. [2]Optically, Ga-La-S has a high refractive index, a transmission window covering most of the visible wavelengths and extending to about 10 μm and a low maximum phonon energy, approx. 450 cm −1.
The force of gravity (red), the buoyancy force (green), and the resultant centripetal force (blue) In the following discussion, represents the acceleration due to gravity, represents the angular speed of the liquid's rotation, in radians per second, is the mass of an infinitesimal parcel of liquid material on the surface of the liquid, is the distance of the parcel from the axis of rotation ...
Liquid Metal may refer to: A liquid metal, which has a relatively low melting point, such as mercury, tin or lead; Any metal in a liquid state; Mercury, the only metal to be liquid at room temperature; Liquid metallic hydrogen; Liquidmetal, a type of metallic glass; Liquid Metal (Sirius XM), a radio channel
