Many bismuth alloys have low melting points and are found in specialty applications such as solders. Many automatic sprinklers, electric fuses, and safety devices in fire detection and suppression systems contain the eutectic In 19.1 -Cd 5.3 -Pb 22.6 -Sn 8.3 -Bi 44.7 alloy that melts at 47 °C (117 °F) [ 18 ] This is a convenient temperature ...
1802 K. 1529 °C. 2784 °F. The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
Infobox references. Bismuth (III) oxide is a compound of bismuth, and a common starting point for bismuth chemistry. It is found naturally as the mineral bismite (monoclinic) and sphaerobismoite (tetragonal, much more rare), but it is usually obtained as a by-product of the smelting of copper and lead ores.
Bismuth telluride (Bi2Te3) is a gray powder that is a compound of bismuth and tellurium also known as bismuth (III) telluride. It is a semiconductor, which, when alloyed with antimony or selenium, is an efficient thermoelectric material for refrigeration or portable power generation. Bi2Te3 is a topological insulator, and thus exhibits ...
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. ... Bismuth: 9.807: 544.7: 1,837
A stoichiometric mixture of elemental bismuth and selenium, when heated above the melting points of these elements in the absence of air, will become a liquid that freezes to crystalline Bi 2 Se 3. [27] Large single crystals of bismuth selenide can be prepared by the Bridgman–Stockbarger method. [28]
Melting point: 227 °C (441 °F; 500 K) Boiling point: ... Bismuth chloride (or butter of bismuth) is an inorganic compound with the chemical formula BiCl 3.
Lead-Bismuth Eutectic or LBE is a eutectic alloy of lead (44.5 at%) and bismuth (55.5 at%) used as a coolant in some nuclear reactors, and is a proposed coolant for the lead-cooled fast reactor, part of the Generation IV reactor initiative. It has a melting point of 123.5 °C/254.3 °F (pure lead melts at 327 °C/621 °F, pure bismuth at 271 ...
