摘要：

The tin-metal mixed hydroxides CaSn(OH)6, MnSn(OH)6, CoSn(OH)6, and ZnSn(OH)6, with cubic morphol-ogies, were prepared using a coprecipitation method; they were subsequently transformed into the correspond-ing tin-metal mixed oxides by calcination at 600-900 degrees C. The crystalline structures and the morphologies of the various samples at each calcination step (just prepared, dried at 110 degrees C, and calcined at 600 and 900 degrees C) were systematically evaluated by X-ray diffractometry, scanning electron microscopy, transmission electron micros-copy, and X-ray absorption fine structure analyses. The cubic shapes of the CaSn(OH)6 and ZnSn(OH)6 nanoparticles were maintained after calcination of them at 600 and 900 degrees C, while those of MnSn(OH)6 and CoSn(OH)6 ones were not maintained after calcination of them.
