The Role of Crystal Control Agent in the Formation of Needlelike Calcium Carbonate Nano Particles

Abstract:

Article Preview

In this work, needlelike precipitated calcium carbonate (PCC) nanometer particles were synthesized by industrial carbonation route using EDTA as crystal control agent. The morphological characterization shows that the as-synthesized needlelike PCC particles have an average diameter of 52 nm and an aspect ratio of around 14:1. The results indicate that EDTA plays a crucial role in the formation of needlelike PCC nanometer particles. A possible mechanism for the formation of needlelike PCC particles assisted by the crystal control agent EDTA is also proposed.
