Morphosynthesis of CaCO3 at different reaction temperatures and the effects of PDDA, CTAB, and EDTA on the particle morphology and polymorph stability
Facile precipitation of CaCO3 was performed using aqueous solutions of CaCl2 with
Na2CO3 over a wide range of mixing and aging temperatures. The precipitation process
was then repeated in the presence of PDDA, CTAB, and EDTA at the mixing temperatures of
30° C, 50° C, 70° C, and 90° C. The presence of these additives was seen to greatly
suppress the formation of aragonite. Among these additives, EDTA was the one that showed
the most prominent effects on particle morphology of CaCO3. The sequence of pH …

The sequence of pH adjustment appeared to be a critical factor for the additive functionality.
