| Hazard Information | Back Directory | [Chemical Properties]
White crystals.
Slightly soluble in water. | [Uses]
Metaboric can be prepared in three crystal forms; orthorhombic α, monoclinic β, cubic γ. 1 Detailed study of the monoclinic and cubic structures of the acid has been reported. Metaboric acid can be obtained by heating boric acid at 120oC for 4h. | [General Description]
Metaboric can be prepared in three crystal forms; orthorhombic α, monoclinic β, cubic γ. 1 Detailed study of the monoclinic and cubic structures of the acid has been reported. Metaboric acid can be obtained by heating boric acid at 120oC for 4h. | [Synthesis]
Metaboric acid occurs when H3BO3 is heated to 80-100°C for several days, either in an oven or in a dry air stream, until the calculated amount of water has been removed. |
