WebThe crystal structures of the fluorapatites from Cheever, Mineville, Palmer Hill, Arnold Hill, and Rutgers mine were analyzed. Rare earth elements (REE) are dominant at the Ca2 site, and in the most REE-rich sample, from Cheever, 5.7% of the Ca2 sites and 3.5% of the Ca1 sites are occupied by REEs. The difficulty of predicting stable crystal structures based on the knowledge of only the chemical composition has long been a stumbling block on the way to fully computational materials design. Now, with more powerful algorithms and high-performance computing, structures of medium complexity can be predicted using such approaches as evolutionary algorithms, random sampling, or metadynamics.
