【Abstract】 The new mixed borates with formula （Rb₂Ca[B₄O₅（OH）₄]₂·8H₂O and Cs₂Ca[B₄O₅（OH）₄]₂·8H₂O） were prepared by the reaction Rb（Cs）-borate aqueous solution with CaCl₂. 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.更多还原
