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.
Tuzlaite is a borate mineral, associated with halides, named after the Tuzla salt mines in Bosnia and Hercegovina. A multitude of rare evaporate minerals have been discovered there, it being the only major evaporate deposit in the Balkans. [4] This mineral has been approved as tuzlaite by the International Commission on New Minerals and Mineral ...
Takedaite is a borate mineral that was found in a mine in Fuka, Okayama Prefecture Japan during a mineralogical survey in the year 1994. During the survey, Kusachi and Henmi reported the occurrence of an unidentified anhydrous borate mineral closely associated with nifontovite, olshanskyite, and calcite.

Borate fusion and energy dispersive X-ray fluorescence spectrometry with polarized excitation have been used in the analysis of contaminated soils. [14] Disodium octaborate tetrahydrate Na 2 B 8 O 13 ·4H 2 O (commonly abbreviated DOT) is used as a wood preservative or fungicide. Zinc borate is used as a flame retardant.
Ulexite is a borate mineral because its formula (NaCaB 5 O 6 (OH) 6 ·5H 2 O) contains boron and oxygen. The isolated borate polyanion [B 5 O 6 (OH) 6] 3− has five boron atoms, therefore placing ulexite in the pentaborate group. Ulexite is a structurally complex mineral, with a basic structure containing chains of sodium, water and hydroxide ...
Béhierite is a very rare borate mineral, [2] and the tantalum endmember of a (Nb,Ta)BO 4 solid solution series formed with schiavinatoite, its niobium analogue. [4] [3] Béhierite is also one of the most simple tantalum minerals. It contains simple tetrahedral borate anions, instead of more common among minerals, planar BO 3 groups.
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 .
