METABORIC ACID Usage And Synthesis

Chemical Properties

White crystals. Slightly soluble in water.

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 120^oC 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.
