摘　　要：The FT-IR difference spectroscopy and the Raman spectroscopy were used to ide ntify the polyborate ions in saturated aqueous solutions during dissolution and transformation of 2MgO·2B2O3·MgCl2·14H2O in different HCl solutions at 30℃. The assignments of the recorded IR-Spectroscopic frequencies and Raman shift of the borate aqueous solution are given. The existing forms of polyborate anions in saturated aqueous solution and their interaction have been discussed. The rel ationships between the existing forms of polyborate anions and the crystallizing solid phases have been gained.The FT-IR difference spectroscopy and the Raman spectroscopy were used to identify the polyborate ions in saturated aqueous solutions during dissolution and transformation of 2MgO . 2B(2)O(3) .
