摘要
采用Rb2 CO3 ,Cs2 CO3 ,H3 BO3 和CaCl2 合成了新的硼氧酸盐复盐Rb2 Ca[B4O5(OH) 4 ]2 ·8H2 O和Cs2 Ca[B4O5(OH) 4 ]2 ·8H2 O ,通过化学分析和热分析等确定了化学物的组成。给出了两种化合物的FTIR光谱和Ra man光谱 ,分析了各种谱线的归属。
The new mixed borates with formula (Rb_2Ca[B_4O_5(OH)_4]_2·8H_2O and Cs_2Ca[B_4O_5(OH)_4]_2·8H_2O) were prepared by the reaction Rb(Cs)-borate aqueous solution with CaCl_2. The compositions of the compounds were determined by chemical analysis and thermal analysis etc. Infrared (4 000-400 cm -1 ) and Raman (4 000-500 cm -1 ) spectra of these samples were recorded at room temperature and analyzed. Fundamental vibrational modes were indentified and band assignments were made.
