Dihexadecyl Phosphate-Assisted Synthesis of Unusual Calcium Carbonate Microspherules
The interesting finding is reported that unusual calcium carbonate (CaCO3) microspherules had been synthesized by simply mixing calcium chloride and ammonium bicarbonate with the assistance of dihexadecyl phosphate (DHP, an anionic lipid). The experimental results indicate that as-prepared CaCO3 microspherules with complex surface texture are predominantly vaterite with high stability. DHP plays a critical role in the formation of the well-defined CaCO3 microspherules.
