The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, ... 83 Bi bismuth; use: 544.7 K: 271.5 °C: 520.7 °F WEL ...
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) [ 19 ] This is a convenient temperature ...

The monoclinic α-phase transforms to the cubic δ-Bi 2 O 3 when heated above 729 °C, which remains the structure until the melting point, 824 °C, is reached. The behaviour of Bi 2 O 3 on cooling from the δ-phase is more complex, with the possible formation of two intermediate metastable phases; the tetragonal β-phase or the body-centred ...
Bismuth telluride (Bi 2 Te 3) 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.
Melting point: 500 °C (932 °F; 773 K) Solubility in water. ... Bismuth vanadate is the inorganic compound with the formula BiVO 4. It is a bright yellow solid.
Bismuth subcarbonate (BiO) 2 CO 3, sometimes written Bi 2 O 2 (CO 3) is a chemical compound of bismuth containing both oxide and carbonate anions. Bismuth is in the +3 oxidation state. Bismuth subcarbonate occurs naturally as the mineral bismutite. Its structure [1] consists of Bi–O layers and CO 3 layers and is related to kettnerite, CaBi(CO ...
