  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 ...

  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 ...

    The phase composition of a particular cement can be quantified through a complex set of calculation known as the Bogue formula. To avoid the flash setting of concrete, due to the very fast hydration of the tricalcium aluminate ( C 3 A ), 2–5 wt. % calcium sulfate is interground with the cement clinker to prepare the cement powder.

  6. Sodium superoxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_superoxide

    Sodium superoxide is the inorganic compound with the formula Na O 2. [1] This yellow-orange solid is a salt of the superoxide anion. It is an intermediate in the oxidation of sodium by oxygen.

  7. Sodium oxalate - Wikipedia

    en.wikipedia.org/wiki/Sodium_oxalate

    Sodium oxalate, or disodium oxalate, is a chemical compound with the chemical formula Na 2 C 2 O 4. It is the sodium salt of oxalic acid. It contains sodium cations Na + and oxalate anions C 2 O 2− 4. It is a white, crystalline, odorless solid, that decomposes above 290 °C. [2]

  8. Sodium metaborate - Wikipedia

    en.wikipedia.org/wiki/Sodium_metaborate

    Sodium metaborate is a chemical compound of sodium, boron, and oxygen with formula NaBO 2. [3] However, the metaborate ion is trimeric in the anhydrous solid, therefore a more correct formula is Na 3 B 3 O 6 or (Na +) 3 [B 3 O 6] 3−. The formula can be written also as Na 2 O·B 2 O 3 to highlight the relation to the main oxides of sodium and ...
