Abstract: Calcium carbonate is one of most abundant biological minerals. Calcium carbonate with multi-morphologies and different polymorphs can be used in different fields,including printing,ceramics,paints,and medicine. The template method is preferable to other approaches for synthesis of calcium carbonate,as its morphology and polymorph can be effectively controlled by simply altering the nature of template and preparation conditions. This paper reviews the development in preparation of calcium carbonate by using small molecule,natural macromolecule,gel,microemulsion and polymer as soft templates. The synthesis of calcium carbonate by using hard template is also described. The main development directions and problems in preparing calcium carbonate are analyzed by comparing the advantages and disadvantages of various matrixes. Finally,preparation of calcium carbonate and other biomaterials with the template method is prospected. The mechanism of synthesis of calcium carbonate with the template method,and using electrochemistry and other modern technology to improve the technology of controlling polymorphs and morphologies of calcium carbonate should be focused in the future.
