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.
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.
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 ...
Fluoborite has a chemical formula of Mg 3 (BO 3)(F,OH) 3.Its name comes from its main chemical components, fluorine and boron.It was first described in 1926. [3]Fluoborite's crystal system is hexagonal, meaning it has one six-fold axis of rotation.
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.
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.
Schiavinatoite is a very rare borate mineral, [3] and the niobium endmember of a (Nb,Ta)BO 4 solid solution formed with béhierite. [4] Schiavinatoite is classified as monoborate. It contains tetrahedral borate anion instead of planar BO 3 group, which is more common among minerals. Schiavinatoite is one of the most simple niobium minerals.
Lithium is used for lithium batteries; boron is used in alloys, ceramic, glasses, and other applications. [6] It was originally estimated that there are 200 million tons of the lithium borate ore, which would make the future Jadar mines one of the world's largest lithium deposits, supplying 10% of the world's demand for lithium.
