  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.

  3. Sodium peroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_peroxide

    Sodium peroxide is an inorganic compound with the formula Na 2 O 2.This yellowish solid is the product of sodium ignited in excess oxygen. [3] It is a strong base. This metal peroxide exists in several hydrates and peroxyhydrates including Na 2 O 2 ·2H 2 O 2 ·4H 2 O, Na 2 O 2 ·2H 2 O, Na 2 O 2 ·2H 2 O 2, and Na 2 O 2 ·8H 2 O. [4] The octahydrate, which is simple to prepare, is white, in ...

  6. Soda lime - Wikipedia

    en.wikipedia.org/wiki/Soda_lime

    Soda lime canister used in anaesthetic machines to act as a carbon dioxide scrubber. Soda lime, a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO), is used in granular form within recirculating breathing environments like general anesthesia and its breathing circuit, submarines, rebreathers, and hyperbaric chambers and underwater habitats.

  7. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    An oxide is a chemical compound in which one or more oxygen atoms combined with another element, such as H 2 O or CO 2.Based on their acid-base characteristics, oxides can be classified into four categories: acidic oxides, basic oxides, and amphoteric oxides and neutral oxides.

  8. Glass bead road surface marking - Wikipedia

    en.wikipedia.org/wiki/Glass_bead_road_surface...

    Carbon dioxide produced by the decomposition of calcium carbonate and sodium carbonate is removed to obtain the required retroreflective properties of the glass. In addition, both arsenic and antimony are used as decolorizers. Having a colorless glass is crucial to maximizing retroreflectivity.

  9. Sodium superoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_superoxide

    NaO 2 is prepared by treating sodium peroxide with oxygen at high pressures: [2]. Na 2 O 2 + O 2 → 2 NaO 2. It can also be prepared by careful oxygenation of a solution of sodium in cryogenic liquid ammonia:
