Vaterite has broad application prospects in the field of daily necessities and biomedical science because of its unique mechanical, physical and chemical properties. However, vaterite is the thermodynamically least stable phase in the three anhydrous crystalline phases of calcium carbonate, and such thermal metastability often transforms it into more stable aragonite or calcite phases, so how to inhibit the phase transformation of vaterite is always a hot topic in the study of calcium carbonate. In this paper, structure, properties, application, and phase transformation from vaterite to aragonite and/or calcite are briefly introduced. Particularly, based on the three basic routes of synthesis of calcium carbonate, some traditional methods, such as carbonization, double decomposition, microemulsion, solvothermal method, and some latest progress, e.g. self-assembly of monolayer, biomimetic synthesis and thermal decomposition methods of tuning and preparation on vaterite are then summarized. Moreover, some analysis on the mechanism of

“…Owing to its low cost, abundance, and excellent biocompatibility, calcium carbonate (CaCO 3 ) is a frequently used filler in the paper, plastic, rubber, and food sectors [1][2][3]. Carbonation [4], complicated decomposition [5], and pyrolysis [6] are the most common techniques used to produce calcium carbonate. Although well developed, the conventional production methods have drawbacks such as high energy consumption and the depletion of natural ores [2,7,8].…”

To avoid the long-term pollution of land and water by industrial gypsum by-products, the exploitation of this resource has become a priority. The indirect synthesis of calcium carbonate from the industrial by-product gypsum has received substantial attention as a viable method for resource utilization. Currently, the primary problems in the indirect manufacture of calcium carbonate from the industrial by-product gypsum are additive recycling and process simplification. This paper describes the present state of development and compares various indirect mineralization systems. The factors affecting leaching and mineralization in the indirect mineralization of CO2 from by-product gypsum and the management of CaCO3 crystallinity are discussed, and the current additive regeneration cycle is summarized. The applications of other technologies in the indirect mineralization of by-product gypsum are also summarized, as are the obstacles, and required future work. This review provides guidelines for the laboratory indirect mineralization of by-product gypsum as well as practical applications.
