Calcium carbonate WikipediaPreparation of Vaterite Calcium Carbonate in the Form of

Calcium carbonate is a chemical compound with the formula Ca CO 3 It is a common substance found in rocks as the minerals calcite and aragonite most notably as limestone which is a type of sedimentary rock consisting mainly of calcite and is the main component of pearls and the shells of marine organisms snails and eggsIt is supposed that the core shell structured microspheres with the nanoparticles are attributed to the adsorption of PSS on the faces of calcium carbonate crystals The results revealed that polycarboxylate superplasticizer can use in preparation of vaterite calcium carbonate from aqueous solutions
