Polymorphic Changes of calcite Carbonate Sediment in Aqueous Solution
Calcium carbonate (CaCO3) is abundant in nature,and is also an important material applied in industry as pigment,filler material,etc.It is a challenge to control the desired CaCO3 properties for industry applications.In this study,three typical morphologies of CaCO3,calcite,aragonite and vaterite were prepared.The crystallization temperature and addition of acrylic-acrylate-sulfosait copolymer play a significant effect on the polymorph change of CaCO3 sediment.Higher temperature promoted the formation of aragonite,while more additives tended to form the vaterite.The x-ray diffraction and scanning electron microscope analysis confirmed the formation of CaCO3 with various polymorphs.
