Lanthanum phosphate powders were synthesised from precipitation using three different routes. Depending on synthesis conditions, these powders have the monoclinic structure of monazite (LaPO4) or the hexagonal structure of rhabdophane (LaPO4,0.5H2O). Chemical analysis gave a La/P ratio of about 0.9. Rhabdophane phase remained stable up to 650°C and transformed into monazite at higher temperature.
