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.
Zinc and vitamin D are also essential for bone health but have the added benefit for men over 50 by reducing the risk of erectile dysfunction, a condition commonly affecting men over age 40 ...
Many common brand supplements in the United States contain levels above the DRI/RDA amounts for some vitamins or minerals. Severe vitamin and mineral deficiencies require medical treatment and can be very difficult to treat with common over-the-counter multivitamins. In such situations, special vitamin or mineral forms with much higher ...
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]
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.
Boracite is a magnesium borate mineral with formula: Mg 3 B 7 O 13 Cl. It occurs as blue green, colorless, gray, yellow to white crystals in the orthorhombic - pyramidal crystal system . Boracite also shows pseudo-isometric cubical and octahedral forms.
Chambersite is a manganese borate mineral with formula Mn 3 B 7 O 13 Cl. It is a member of the borate mineral series [5] that includes other minerals such as ericaite (Fe 3 B 7 O 13 Cl) and boracite (Mg 3 B 7 O 13 Cl). [6] When chambersite was first discovered, it was the second chemical analogue of boracite to be found in nature. [7]
