The Synthesis and Characterization of Rare-Earth Fluocarbonates

摘要

abstract_textpA procedure is described for synthesizing cerium fluorcarbonate. This synthetic bastnaesite was characterized through X-Ray diffraction, chemical analysis and thermogravimetric studies. The solubility product of Ce-bastnaesite was determined to be 10(-10.1). The stability constant pK CeHCO32+ complex was experimentally determined to be 3.04 +/- 0.21. Based on the thermodynamic data available in the literature, a speciation diagram has been prepared for the synthetic cerium bastnaesite./p/abstract_text
