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).
