The influence of organic additives, β-cyclodextrin, HEDTA, L-aspartic acid and L-glutamic acid on crystal growth of calcium carbonate via vapour diffusion method has been investigated.In the absence of additive,regular rhombohedral calcium carbonate crystal habitresulted. Whereas in presence of additive, calcite with truncated, aggregated rhombohedral sub crystals and elongated hexagonal morphologies resulted. The obtained calcium carbonate phases were characterized by SEM, Powder XRD and FT-IR.
