Pure Nd- and La-hydroxylbastnasite, and Nd-kozoite crystals were synthesized hydrothermally as described by Vallina et al. (2014) to obtain minerals with pure end-member compositions. Briefly, aqueous solutions with a concentration of 50 mM of the desired REE-chloride were mixed with 50 mM Na 2CO 3 solutions at ambient temperature,
  • Bastnäsite - Wikipedia

    en.wikipedia.org/wiki/Bastn%C3%A4site The mineral bastnäsite (or bastnaesite) is one of a family of three carbonate-fluoride minerals, which includes bastnäsite-() with a formula of (Ce, La)CO 3 F, bastnäsite-() with a formula of (La, Ce)CO 3 F, and bastnäsite-() with a formula of (Y, Ce)CO 3 F. Some of the bastnäsites contain OH − instead of F − and receive the name of hydroxylbastnasite.
