Malonic acid was utilized to inhibit the precipitation kinetics of calcium carbonates. It was found that higher malonic acid concentrations added into the precipitating CaCO3 solution resulted in less calcite fractions (under identical precipitation times).
Similarly, prolonged precipitation times yielded less calcite fractions for the experiments using malonic acid as compared to the experiments in a pure system, i.e. when no malonic acid was added.
As is known calcium carbonate precipitation would normally yield three crystalline phases: vaterite, aragonite, and calcite (and the amorphous precursor).
What is the mechanism of CaCO3 phase transformation under the influence of malonic acid?
