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 ...
Borate anions are largely in the form of the undissociated acid in aqueous solution at physiological pH. No further metabolism occurs in either animals or plants. In animals, boric acid/borate salts are essentially completely absorbed following oral ingestion. Absorption occurs via inhalation, although quantitative data are unavailable.
Takedaite is a borate with the presence of calcium, boron and oxygen. Chemical analysis gave CaO 71.13%, B 2 O 3 28.41%, the H 2 O content was determined by ignition loss at 900°C and was 0.14%, totaling 99.68%. The empirical formula calculated on the basis of O=6 is therefore Ca 3.053 B 1.965 O 6 or more ideally Ca 3 B 2 O 6. [4]
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula B(OH) 3. It may also be called hydrogen orthoborate, trihydroxidoboron or boracic acid. [3] It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite.
Zinc borate refers to a family of inorganic compounds consisting of borate of zinc.They are white solids with the formulas 4ZnO·B 2 O 3 ·H 2 O, ZnO·B 2 O 3 ·1.12H 2 O, ZnO·B 2 O 3 ·∼2H 2 O, 6ZnO·5B 2 O 3 ·3H 2 O, 2ZnO·3B 2 O 3 ·7H 2 O, 2ZnO·3B 2 O 3 ·3H 2 O, 3ZnO·5B 2 O 3 ·14H 2 O, and ZnO·5B 2 O 3 ·4.5H 2 O.
The compound is also called trisodium orthoborate, sodium orthoborate, or just sodium borate. However, "sodium orthoborate" has been used also for a compound with formula Na 4 B 2 O 5 , which would correspond to an equimolar mixture of sodium metaborate NaBO 2 and trisodium borate proper.

Disodium octaborate is a borate of sodium, a chemical compound of sodium, boron, and oxygen — a salt with elemental formula Na 2 B 8 O 13 or (Na +) 2 [B 8 O 13] 2−, also written as Na 2 O·4B 2 O 3. It is a colorless crystalline solid, soluble in water.
