摘　　要：在常温常压条件下直接合成了硼磷酸盐NaCd(H2O)2[BP2O8·]0.8H2O(Hexagonal,P6122,a=0.97130(14)nm,c=1.6136(3)nm,V=1.31836(40)nm3,Z=6)和NaZn(H2O)2[BP2O8]·H2O(Hexagonal,P6122,a=0.95404(2)nm,c=1.47780(3)nm,V=1.16488(5)nm3,Z=6)。用粉末XRD表征了合成产物。用扫描电镜观察了不同温度下形成的产物的形态。通过实时XRD监测方法研究了常温常压下硼磷酸盐NaZn(H2O)2[BP2O8·]H2O的形成过程。NaCd (H2O)(2)[BP2O8]center dot 0.8H(2)O and NaZn (H2O)(2) [BP(2)O(8)center dot H2O have been synthesized under room temperature and ambient pressure. The two borophosphates were characterized by powder X-ray diffraction. Their morphology were observed by SEM. The formation procedure of NaZn(H2O)(2)[BP2O8]center dot H2O was studied by in situ powder X-ray diffraction.
