Abstract

The ammonium biborate tetrahydrate was synthesized by stoichiometric incorporation of boric acid and ammonium hydroxide in aqueous solution and the effects of supersaturation, temperature, pH of solution, cooling rate and presence of impurities upon the metastable zone width (MZW) were investigated. The MZW of ammonium biborate tetrahydrate aqueous solution was increased with increasing concentration of impurities. The saturation temperature was increased in the presence of Ca (II) ion and decreased in the presence of Pb(II) and Mg (II) ions.
