Abstract
The monodisperse micrometer hollow zirconia sphere was prepared in mixed solvents. It was fabricated by using the preformed poly(styrene-acrylic acid) (PSA) as template spheres which was mixed with zirconyl chloride octahydrate in ethanol solvent under steam treatment. The hollow zirconia spheres obtained by the calcination of PSA/ZrO2 composite spheres had a narrow particle size distribution and commendable surface topography characterized by SEM. The calcined hollow zirconia spheres displayed monoclinic crystalline reflection peaks characterized by XRD. Besides, the micro-morphology, composition and molecular composition of sample were analyzed by FESEM, TG–DSC and FTIR, respectively.
