Abstract: Supersaturated aqueous solution of MgO·2B2O3-H2O, Na2O·5B2O3-H2Oand MgO·3B2O3-H2Owere prepared. Raman spectra of the solutions have been obtained. The results show that there exist various polyborate anions in the supersaturated aqueous solutions. The assignments of the recorded frequencies of the borate aqueous solution were given. The interaction mechanism between polyborate ions in supersaturated solution was discussed.

Key words: Raman spectra, Borate, Supersaturated aqueous solution, Polyborate anion
