Ce3+ activated LaCl3 is a promising scintillation crystal for radiation detection. The starting raw materials used to grow LaCl3 crystals are rather hygroscopic and XRD proves that LaCl3·7H2O and LaCl

The dehydration schemes of LaCl3·7H2O, CeCl3·7H2O, PrCl3·7H2O, PrCl3·7H2O, EuCl3·6H2O, GdCl3·OH2O, HoCl3·6H2O, ErCl3·OH2O, TmCl3·6H2O, YbCl3·OH2O and YCl3·6H2O have been investigated by the isothermal fluidizedbed technique. This technique is based on the fact that reactions proceed at a close approach to equilibrium and thus give rise to constant reaction rate regimes at constant gas flow and temperature in the bed. By injecting a small portion of HCl(g) (～1%) into the gas stream, hydrolysis is avoided, and dehydration to the monohydrate is recorded by both thermal analysis of the preheated inlet gas and chemical analysis of samples taken from the bed. Based on the present results, together with previous results on NdCl3·OH2O, TbCl3·6H2O and DyCl3·6H2O, dehydration schemes of all rare-earth chlorides except LuCl3 and ScCl3 are suggested.
