Structure and phase analysis of calcium carbonate powder prepared by a simple solution method

This paper focused on the analysis of the crystal structure and phase transformation of CaCO3 synthesized by simple solution method from 0.5 M Ca(NO3)2 precursor and 0.5 M Na2CO3 precipitant at ambient temperature (300 K). The pH of the sample solution at various reaction times of 5, 10, 15, and 30...
