中文摘要：
利用Stoeber种子生长法，第一次在尺寸为2μm左右的碳酸镉菱形微粒表面直接包覆二氧化硅层，得到碳酸镉@二氧化硅核壳结构的胶体粒子．作为核壳结构的壳层部分，二氧化硅层的厚度可以通过加入体系中的正硅酸乙酯的量来控制．作为核层的碳酸镉胶体部分可以被盐酸刻蚀掉，进而得到具有菱形体空心结构的二氧化硅微粒．
英文摘要：
We report a facile method to coat rhombohedra CdCO3 microparticles with SiO2 directly by Stoeber seed growth method. CdCO3 @ SiO2 core-shell colloid particles were obtained, and the thickness of the SiO2 shell can be modulated in a certain range by adjusting the amount of tetraethyl orthosilicate （TEOS） which was added into the system. As a result, a new species was found which can be coated with SiO2 without surface modification. Furthermore, after removal CdCO3 particles with hydrochloric acid, hollow rhombohedra SiO2 particles were obtained which can be further used as microreactors and so on.
