In animals, boric acid/borate salts are essentially completely absorbed following oral ingestion. Absorption occurs via inhalation, although quantitative data are unavailable. Limited data indicate that boric acid/salts are not absorbed through intact skin to any significant extent, although absorption occurs through skin that is severely abraded.
Another method is heating boric acid above ~300 °C. Boric acid will initially decompose into steam, (H 2 O (g)) and metaboric acid (HBO 2) at around 170 °C, and further heating above 300 °C will produce more steam and diboron trioxide. The reactions are: H 3 BO 3 → HBO 2 + H 2 O 2 HBO 2 → B 2 O 3 + H 2 O. Boric acid goes to anhydrous ...
Fluoroboric acid is the principal precursor to fluoroborate salts, which are typically prepared by treating the metal oxides with fluoroboric acid. The inorganic salts are intermediates in the manufacture of flame-retardant materials and glazing frits, and in electrolytic generation of boron. H[BF 4] is also used in aluminum etching and acid ...
Some of the anhydrous borates above can be crystallized from molten mixtured of sodium oxide and boric oxide. [6] Some sodium borates hower cannot be analyzed as combinations xNa 2 O·yB 2 O 3 ·zH 2 O of the three ordinary oxides. The most important example is sodium perborate, originally described as NaBO 3 ·H 2 O but actually (Na +) 2 [B 2 ...
