    en.wikipedia.org/wiki/Calcium

    Calcium sulfite is used as a bleach in papermaking and as a disinfectant, calcium silicate is used as a reinforcing agent in rubber, and calcium acetate is a component of liming rosin and is used to make metallic soaps and synthetic resins.

  4. Calciothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Calciothermic_reaction

    Calciothermic reactions are metallothermic reduction reactions (more generally, thermic chemical reactions) which use calcium metal as the reducing agent at high temperature. Calcium is one of the most potent reducing agents available, usually drawn as the strongest oxidic reductant in Ellingham diagrams , though the lanthanides best it in this ...

    The compound [(thf) 3 Ca{μ-C 6 H 3-1,3,5-Ph 3}Ca(thf) 3] also described in 2009 [22] [23] is an inverse sandwich compound with two calcium atoms at either side of an arene. Olefins tethered to cyclopentadienyl ligands have been shown to coordinate to calcium(II), strontium(II), and barium(II): [24] Organocalcium compounds have been ...

  8. Wollastonite - Wikipedia

    en.wikipedia.org/wiki/Wollastonite

    Wollastonite is a calcium inosilicate mineral (Ca Si O 3) that may contain small amounts of iron, magnesium, and manganese substituting for calcium. It is usually white. It forms when impure limestone or dolomite is subjected to high temperature and pressure, which sometimes occurs in the presence of silica-bearing fluids as in skarns [7] or in contact with metamorphic rocks.

  9. Betterton–Kroll process - Wikipedia

    en.wikipedia.org/wiki/Betterton–Kroll_process

    Instead of calcium and magnesium metal being added directly to the mixture, oxides of the metals mixed with other molten salts can be added to the solution. [9] Once in the mixture at high temperature, electrodes can be used to decompose the salts into the metal and oxygen gas, so the calcium and magnesium are free to form alloys in the solution.
