  2. Bismuth - Wikipedia

    en.wikipedia.org/wiki/Bismuth

    Bismuth dissolves in concentrated sulfuric acid to make bismuth(III) sulfate and sulfur dioxide. [34] 6 H 2 SO 4 + 2 Bi → 6 H 2 O + Bi 2 (SO 4) 3 + 3 SO 2. It reacts with nitric acid to make bismuth(III) nitrate (which decomposes into nitrogen dioxide when heated [39]). [40] Bi + 6 HNO 3 → 3 H 2 O + 3 NO 2 + Bi(NO 3) 3

    Ruthenium and rhodium are precious metals produced as a small percentage of the fission products from the nuclear fission of uranium.The longest half-lives of the radioisotopes of these elements generated by nuclear fission are 373.59 days for ruthenium and 45 days for rhodium [clarification needed].

  4. Cupellation - Wikipedia

    en.wikipedia.org/wiki/Cupellation

    16th century cupellation furnaces (per Agricola). Cupellation is a refining process in metallurgy in which ores or alloyed metals are treated under very high temperatures and subjected to controlled operations to separate noble metals, like gold and silver, from base metals, like lead, copper, zinc, arsenic, antimony, or bismuth, present in the ore.

  5. Bismuthyl (ion) - Wikipedia

    en.wikipedia.org/wiki/Bismuthyl_(ion)

    Previously, it was believed that bismuthyl plays almost the main role in the geochemistry of bismuth and metamorphic processes taking place in a liquid medium. Already in ore waters, bismuth and its main compounds are oxidized, forming a sparingly soluble oxychloride — bismoclite, which, when mixed with bicarbonate background waters, is replaced by an even more sparingly soluble — bismuthite.

  9. Bismuth compounds - Wikipedia

    en.wikipedia.org/wiki/Bismuth_compounds

    Unlike the lighter pnictogens nitrogen, phosphorus, and arsenic, but similar to antimony, bismuth does not form a stable hydride. Bismuth hydride, bismuthine (BiH 3), is an endothermic compound that spontaneously decomposes at room temperature. It is stable only below −60 °C. [5] Bismuthides are intermetallic compounds between bismuth and ...
