Borate ions occur, alone or with other anions, in many borate and borosilicate minerals such as borax, boracite, ulexite (boronatrocalcite) and colemanite. Borates also occur in seawater, where they make an important contribution to the absorption of low frequency sound in seawater. [1] Borates also occur in plants, including almost all fruits. [2]
The Borate Minerals are minerals which contain a borate anion group. The borate (BO 3) units may be polymerised similar to the SiO 4 unit of the silicate mineral class. This results in B 2 O 5, B 3 O 6, B 2 O 4 anions as well as more complex structures which include hydroxide or halogen anions. [2] The [B(O,OH) 4] − anion exists as well.

Trisodium borate is a chemical compound of sodium, boron, and oxygen, with formula Na 3 BO 3, or (Na +) 3 [BO 3] 3−. [3] It is a sodium salt of the orthoboric acid B(OH) 3 . The compound is also called trisodium orthoborate , sodium orthoborate , or just sodium borate .
Fluorooxoborate is one of a series of anions or salts that contain boron linked to both oxygen and fluorine.Several structures are possible, rings, or chains. They contain [BO x F 4−x] (x+1)− units BOF 3 2− BO 2 F 2 3−, or BO 3 F 1 4−.
The borate chlorides are chemical compounds that contain both borate ions and chloride ions. They are mixed anion compounds.Many of them are minerals. Those minerals that crystallise with water (hydrates) may be found in evaporite deposits formed when mineral water has dried out.
In 2001, Herbert Brown and coworkers prepared catecholborane by treatment of tri-o-phenylene bis-borate with diborane. [2] Unlike borane itself or alkylboranes, catechol borane exists as a monomer. This behavior is a consequence of the electronic influence of the aryloxy groups that diminish the Lewis acidity of the boron centre.
Borax (Na 2 B 4 O 5 (OH) 4 · 8 H 2 O [2]) is a borate mineral found in evaporite deposits of alkaline lacustrine environments and as a surface efflorescence in arid regions. It is the chief mineral mined from the deposits at Boron, California and nearby locations, and is the chief source of commercial borax.
