MZr2(AsO4)3(M=Na,K,Rb,Cs)的水热合成与结构表征
Hydrothermal Synthesis and Characterization of MZr2(AsO4),(M=Na, K, Rb, Cs)
【摘要】 用水热晶化法合成了MZr2(ASO4)3(M=Na,K,Rb,Cs)系列化合物。研究了反应物浓度、配比及不同砷源等水热晶化条件对产物物相的影响。用XRD、IR和Raman光谱对产物进行了表征。4种晶体的振动光谱由钠到铯呈现出规律性变化。
【Abstract】 MZr2(AsO4)3(M = Na, K, Rb, Cs) compounds were synthesized under hydrothermal conditions: As2O5/ZrO2 = 6. 4 , M+/As=0. 333 (molar ratio), pH≤,2. 0, 250℃, 5 days. The influence of the concentration and source of reactants on the product phases was investigated. The products were characterized by means of X-ray powder diffraction, Raman and IR spectroscopies. The effect of M+ on the vibrational spectrum of anionic skeleton was preliminarily analyzed.
