Preparation of Ultra-fine Calcium Carbonate by a Solvent-free Reaction using Supersonic Airflow and Low Temperatures

Y-H Cai, D-M Ma, R-F Peng, S-J Chu

Abstract


The treatment of calcium chloride with sodium carbonate under solvent-free conditions with a supersonic airflow and at a low heating temperature leads to the synthesis of ultra-fine calcium carbonate. The reaction not only involves mild conditions, a simple operation, and high yields but also gives a high conversion rate.

Keywords: Supersonic airflow, solvent-free reaction, low temperature, calcium carbonate
