Abstract
The effect of hydrothermal synthetic conditions on the obtaining of lanthanide orthophosphates LnPO4 (Ln = La, Pr, Nd, Sm) with different structure, size and shape of particles was revealed. The optimum conditions for preparation of anhydrous nanoscale lanthanide orthophosphates with monoclinic structure were determined. The prepared nanowhiskers had lengths ranging from 0.4 µm (for LaPO4) to 5 µm (for SmPO4), and the diameter – from 30 nm (for LaPO4) to 200 nm (for SmPO4). The size of particles synthesized under similar conditions increased with decreased of lanthanide ion radius.
