We examined the crystallization impact of the surfactant, 2-aminonicotinic acid and/or β-cyclodextrin on the formation of two anhydrous metal carbonates, MCO3 (M = Ca2+ and Sr2+), from their respective calcium chloride and strontium chloride salts along with NaHCO3 at room temperature. By varying the concentrations of this hybrid surfactant to the concentrations of MCO3 during the preparations and examined their particle sizes by PXRD, FTIR, TGA and SEM. The characterization on these newlyformed anhydrous metal carbonates clearly indicated that CaCO3 formed with three different shapes such as truncated calcite, hexagonal calcite and rod shaped aragonite. Whereas, SrCO3 formed with two different shapes such as hexagonal poles and bloom scale bars by varying concentrations of the surfactants. The mixed surfactant certainly made an impact on the metal carbonates formations with different shapes and sizes by varying surfactants concentrations and conditions.
