Influence of vitamin B3 on morphosynthesis of CaCO3, BaCO3 and SrCO3 micro and nano structures

Influence of vitamin B3, nicotinic acid has been investigated on crystallization of CaCO3, BaCO3 and SrCO3 as a growth modifier. Well-defined crystals with size range from micro-scale to nano-scale can be easily obtained. Different polymorphs of CaCO3, aggregates of hexagonal rods to nano fibers of BaCO3 and dendrimeric nano structures of SrCO3 could be formed, depending on the reaction conditions. Mineralization of alkali metal carbonates controlled by nicotinic acid is a simple and versatile method for production of materials with different morphologies. The concentration of nicotinic acid has significant influence on the size and growth of the final product. The synthesized products were characterized by X-ray diffraction, FT-IR and Scanning Electron Microscopy (SEM)
