The synthesis methods, crystal structures, and properties of anhydrous monazite and xenotime (REPO) crystalline materials are summarized within this review. For both monazite and xenotime, currently available Inorganic Crystal Structure Database data were used to study the effects of incorporating different RE cations on the unit cell parameters, cell volumes, densities, and bond lengths. Domains of monazite-type and xenotime-type structures and other AXO compounds (A = RE; X = P, As, V) are discussed with respect to cation sizes. Reported chemical and radiation durabilities are summarized. Different synthesis conditions and chemicals used for single crystals and polycrystalline powders, as well as first-principles calculations of the structures and thermophysical properties of these minerals are also provided.
本综述总结了无水独居石和磷钇矿(REPO)晶体材料的合成方法、晶体结构和性质。对于独居石和磷钇矿,利用目前可用的无机晶体结构数据库数据,研究了掺入不同稀土阳离子对晶胞参数、晶胞体积、密度和键长的影响。讨论了独居石型和磷钇矿型结构域以及其他AXO化合物(A = 稀土;X = 磷、砷、钒)与阳离子尺寸的关系。总结了已报道的化学耐久性和辐射耐久性。还提供了用于单晶和多晶粉末的不同合成条件和化学物质,以及这些矿物结构和热物理性质的第一性原理计算。
