为什么在煅烧时球壳会破裂呢？是不是球壳做的太薄了？有没有多包覆几层，把球壳做厚？

可以试试自组装的方法啊：
The self-assembly of ZnO hollow spherical structures was made by the coordination of CTAB, Zn(NO3)2·6H2O, and ethylenediamine. The initial oriented attachment of the nanorods to the central stems was followed by the formation of complex multi-pod units, and finally the construction of spheres from the multi-pod units. In other words, this hierarchical organization process started from the generation of ZnO nanorods, then the nanorods became aggregated into multipod units, and finally the multipod units aggregated into the hollow microspheres
