Sodium metaborate is a chemical compound of sodium, boron, and oxygen with formula NaBO2. [3] . However, the metaborate ion is trimeric in the anhydrous solid, therefore a more correct formula is Na3B3O6 or (Na+)3[B3O6]3−. The formula can be written also as Na2O·B2O3 to highlight the relation to the main oxides of sodium and boron. [2] .

Sodium perborates are persalts that are hydrolytically unstable because they contain characteristic boron-oxygen-oxygen bonds that react with water to form hydrogen peroxide and stable sodium metaborate (NaBO2.nH2O). This hydrolysis reaction is the basis of the use of perborates as bleaches in detergents at high (70-100 °C) temperature.

Metaborate also refers to any salt or ester of such anion (e.g. salts such as sodium metaborate NaBO2 or calcium metaborate Ca (BO2)2, and esters such as methyl metaborate CH3BO2). Metaborate is one of the boron's oxyanions. Metaborates can …
