Combined Influence of Organic Additives on Growth Morphology of Calcium Carbonate

摘要

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 habit resulted. 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.
