  2. Sodium oxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_oxide

    Sodium oxide is a chemical compound with the formula Na 2 O. It is used in ceramics and glasses. It is a white solid but the compound is rarely encountered. Instead "sodium oxide" is used to describe components of various materials such as glasses and fertilizers which contain oxides that include sodium and other elements. Sodium oxide is a ...

  7. Sodium methoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_methoxide

    Sodium methoxide is prepared by treating methanol with sodium: 2 Na + 2 CH 3 OH → 2 CH 3 ONa + H 2. The reaction is so exothermic that ignition is possible. The resulting solution, which is colorless, is often used as a source of sodium methoxide, but the pure material can be isolated by evaporation followed by heating to remove residual methanol.

  8. Cryolite - Wikipedia

    en.wikipedia.org/wiki/Cryolite

    Molten cryolite is used as a solvent for aluminium oxide (Al 2 O 3) in the Hall–Héroult process, used in the refining of aluminium. It decreases the melting point of aluminium oxide from 2000–2500 °C to 900–1000 °C, and increases its conductivity [18] thus making the extraction of aluminium more economical. [19]
