Synthesis of Calcium Oxalate Particles via Precipitation Stripping: Effect of Molar Ratio Affect Morphological Changes

Harsh Bharatkumar Shukla

Abstract: Calcium oxalate (CaOx), a biomineral occurs in both plant and the animal kingdom. There are three hydrate forms of Calcium oxalate which are crystallized in different morphologies and the natural occurrence is connected with the three minerals whewellite as (COM) monoclinic monohydrate, (COD) weddilite as orthorhombic dehydrate and (COT) caoxite as triclinic trihydrate. Calcium oxalate used as filler and a pigment in coated paper and the cardboard industry to impart brightness. Many parameters like relative super saturation, pH, precipitation time, stirring, presence of inhibitors and surfactants affect the calcium oxalate hydrate forms and their morphology.
