The use of iminodiacetic acid for low-temperature synthesis of aragonite crystal microrods: Correlation between aragonite crystal microrods and stereochemical effects

摘要

The particle size, morphology, crystallization, and growth of calcium carbonate have been widely studied in the presence of organics, biomacromolecules, and biopolymers. Calcium carbonate with regular surface-relief structures has been synthesized by templating methods in the absence of dual negatively charged organic additives. Although a number of attempts have been made, the large-scale synthesis of 90 wt percent aragonite microrods by a facile route has hitherto remained difficult to achieve at temperatures below 60 deg C By using iminodiacetic acid as a crystal growth modifier, aragonite precipitated calcium carbonate (PCC) in the form of single-crystal microrods has been successfully synthesized at lower temperatures.
