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 IRspectroscopies.The effect of M+ on the vibrational spectrum of anionic skeleton was preliminarily analyzed.

Key words: Hydrothermal synthesis, Characterization of structure, Arsenate, MZr2(AsO4)3
