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.
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.
Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6. The larger ...
Suanite is a magnesium borate mineral with formula Mg 2 B 2 O 5.. It was first described in 1953 by Japanese scientist Takeo Watanabe from the University of Tokyo. [4] His first contact with the mineral was during analysis of gold- and copper- bearing skarn minerals from the Hol Kol mine, located in North Korea obtained in 1939.
Magnesium borate, magnesium salicylate, and magnesium sulfate are used as antiseptics. Magnesium bromide is used as a mild sedative (this action is due to the bromide , not the magnesium). Magnesium stearate is a slightly flammable white powder with lubricating properties.
Admontite is a hydrated magnesium borate mineral with formula MgB 6 O 10 ·7H 2 O. Occurrence - In a gypsum deposit. Associations: gypsum, anhydrite, hexahydrite, löweite, eugsterite, pyrite, quartz. It is named after Admont, Austria. Its Mohs scale rating is 2 to 3.
Warwickite is an iron magnesium titanium borate mineral with the chemical formula (Mg Fe) 3 Ti(O, BO 3) 2 or Mg(Ti,Fe 3+, Al)(BO 3)O. It occurs as brown to black prismatic orthorhombic crystals which are vitreous and transparent. It has a Mohs hardness of 3 to 4 and a specific gravity of 3.36. [3] [4]
