Galinstan, a registered trademark of Geratherm Medical, is a eutectic alloy of gallium, indium, and tin which is liquid at room temperature, typically freezing at −19 °C (−2. An alloy is a Solid solution or Homogeneous mixture of two or more elements, at least one of which is a Metal, which itself has Gallium (ˈgæliəm is a Chemical element that has the symbol Ga and Atomic number 31 Indium (ˈɪndiəm is a Chemical element with chemical symbol In and Atomic number 49 Tin is a Chemical element with the symbol Sn (stannum and Atomic number 50 The Celsius Temperature scale was previously known as the centigrade scale. 2 °F). Fahrenheit is a temperature scale named after Daniel Gabriel Fahrenheit (1686–1736 a German Physicist who proposed it in 1724 Due to the low toxicity of its component metals, it finds use as a non-toxic replacement for many applications that previously employed liquid mercury or sodium-potassium alloy (NaK). Mercury (ˈmɜrkjʊri also called quicksilver or hydrargyrum, is a Chemical element with the symbol Hg ( Latinized hydrargyrum Sodium (ˈsoʊdiəm is an element which has the symbol Na( Latin natrium, from Arabic natrun) atomic number 11 atomic mass 22 Potassium (pəˈtæsiəm is a Chemical element. It has the symbol K (kalium from qalīy Atomic number 19 and Atomic mass 39 NaK (næk rhyming with "sack" is an alloy of Sodium (Na and Potassium (K and particularly one that is liquid at room temperatures Composition: 68. 5% Ga, 21. 5% In, 10% Sn. Its name is a portmanteau of gallium, indium, and stannum (Latin for "tin"). Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.
Galinstan tends to wet and adhere to many materials, including glass, which limits its use compared to mercury. The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. The metre or meter is a unit of Length. It is the basic unit of Length in the Metric system and in the International The kelvin (symbol K) is a unit increment of Temperature and is one of the seven SI base units The Kelvin scale is a thermodynamic Wetting is the contact between a liquid and a solid surface resulting from intermolecular interactions when the two are brought together Galinstan is commercially used as a mercury replacement in thermometers due to its nontoxic properties, but the inner tube must be coated with gallium oxide to prevent the alloy from wetting the glass surface. A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a Thermometer consisting of mercury in a Glass An oxide is a Chemical compound containing at least one Oxygen atom as well as at least one other element
Galinstan has higher reflectivity and lower density than mercury; it is investigated as a replacement of mercury in liquid mirror telescopes for astronomy. Liquid mirrors are Mirrors made with reflective liquids The most common liquid used is mercury, but other liquids will work as well (for example Low melting A telescope is an instrument designed for the observation of remote objects and the collection of Electromagnetic radiation. Astronomy (from the Greek words astron (ἄστρον "star" and nomos (νόμος "law" is the scientific study It is also a promising coolant, though its cost and aggressivity are major obstacles for its use. A coolant is a fluid which flows through a device in order to prevent its overheating transferring the heat produced by the device to other devices that utilize or dissipate it Liquid Metal Embrittlement is a phenomenon of practical importance where certain Ductile Metals experience drastic loss in tensile ductility or undergo brittle
Galinstan is difficult to use for cooling nuclear reactors, because indium has high cross section for thermal neutrons, efficiently absorbing them and inhibiting the fission reaction. This article is a subarticle of Nuclear power. A nuclear reactor is a device in which Nuclear chain reactions are initiated controlled Absorption cross section is a measure for the probability of an absorption process The neutron temperature, also called the neutron energy, indicates a free neutron's Kinetic energy, usually given in Electron volts The term
