Calcium carbonate CaCO is a widely used inorganic

Calcium carbonate (CaCO3) is a widely used inorganic material in various industries and it is an abundant mineral comprising approximately 'Splitomicin' 4% of the earths crust occurring as limestone, chalk, and biominerals [1] and [2]. Because of the harmless properties and inexpensiveness, it has been used for a variety of purposes and finds applications in diverse areas such as in the manufacture of toothpastes, lubricants, paints, textiles, plastics, adhesives, waste water treatment, rubber, ink, paper, ceramic materials, food and horticulture [3], [4], [5] and [6]. Therefore, the precipitation of Splitomicin has received much attention of the researchers. Different applications of calcium carbonate necessitate various granulometric, physical and chemical properties. These specific requirements are generally achieved by preparing the substance under carefully controlled conditions with specific morphology, structure, specific surface area, particle size and particle size distribution etc. [4], [7] and [8]. So as to achieve these specific properties, the kinetics of precipitation of calcium carbonate has been thoroughly investigated [9]. For the manufacturing of precipitated CaCO3, the carbonation of lime is industrially practiced method [10] and [11]. In recent years nano-CaCO3 has found large commercial importance because of its utility in diversified areas [12]. Inorganic nano-particle synthesis is a growing area of research and the change in the properties of materials with nanometric scale makes them increasingly suitable for a variety of applications. Some of the properties of nanomaterials like large surface area, different crystal geometries and hydrophobicity make them more suitable for the applications such as surface coatings, photocatalytic degradation, and catalytic activity [13].
