The application field of materials based on lanthanum orthophosphate (LaPO4), including nanomaterials, has been permanently extending recently. The high level of mechanical properties and the compatibility with numerous oxides make it possible to consider the possibility of using lanthanum orthophosphate as a composite material for construction purposes. This application is particularly promising when nanoparticles with quasi-1D morphology (nanorods) are used. The high isomorphic capacity of the LaPO4-based phase for alkaline-earth ions and ions of lanthanides and actinides, high chemical stability, and high radiation hardness make promising the application of this compound as a matrix for immobilization of radioactive wastes.

The possibility of obtaining lanthanum phosphate (LaPO4) by the hydrothermal method is considered in the work. The results of the influence of pH, temperature and time of processing of hydrothermal synthesis on the morphology and structure of monostructured lanthanum phosphate are presented. It has been determined that, with the increase of pH, the morphology of phosphate changes and the size of the crystallites are increased, while the crystal structure changes from hexagonal to monoclinic.
