The present invention is directed to methods for solubilizing boric acid to prod uce liquid, boron-containing solutions. In these methods, boric acid is added to a p reviously formed solution of a metal ion and ligand. The ligand must be capable of both co mplexing the metal ion and simultaneously coordinating or hydrogen bonding with the boric aci d. Preferred metal ions are the transition metals. Preferred ligands are the alkanolamines, p olyamines, dialkylaminoalkylamines and alkyldiaminecarboxylic acids and salts thereof. Usin g the methods of the present invention, stable, clear solutions, preferrably aqueous s olutions, containing about 9-11 percent-by-weight or more boron are readily prepared.
