Abstract: The calcium carbonate is a stable inorganic compound that exists widely on the earth. Porous calcium carbonate as an inorganic material was commonly used in chemical, pharmaceutical, metallurgy, food and other industries due to its large specific surface area, non-toxic, good biocompatibility, and other advantages. However, the structure, properties and application of porous calcium carbonate were seriously affected by the different fabrication methods or processes that could lead to different structures and crystal forms for porous calcium carbonate. In this paper, some commonly used fabrication methods, such as template method, emulsion liquid membrane method, coprecipitation method, sol-/hydro-thermal method, gel crystallization method and salting method, were introduced. The principles, advantages and disadvantages of various fabrication methods were briefly analyzed. Meanwhile, many research achievements on the application of porous calcium carbonate in various areas were discussed. It is pointed out that the study of porous calcium carbonate at home and abroad was insufficient in certain aspects, such as the difficulty to control precisely its structure and properties, poor energy saving and environmental protection, and the limited utilization of initial materials. It is suggested to explore the application of porous calcium carbonate in waste water and waste gas.
