Abstract: As one of the most extensive industrial raw materials, calcium carbonate is widely used in plastics, rubber, papermaking, coatings, food, medicine, electronics and other industries. Calcium carbonate whiskers with special fibrous morphology have the advantages of low cost, wide sources, and environmental protection of the product itself and production process. Moreover, it has excellent properties such as high strength, high modulus, and high elongation, and it has gradually replaced other costly fiber materials as a reinforcing agent, toughening agent and filler for composite materials. Based on the preparation and industrialization of calcium-based materials for many years, this article discusses the research of calcium carbonate whisker materials in detail from the perspectives of preparation methods and raw materials of calcium carbonate whiskers. The advantages and disadvantages of various current preparation methods of calcium carbonate whiskers are analyzed, and the direction of preparing calcium carbonate whiskers from diverse raw materials such as industrial waste and domestic waste is prospected.
