AbstractAbstract
[en] An efficient method for growth of high optical quality single crystals of PrCl3. The method consists in careful drying of the hydrated chloride, PrCl3. 7H2O, with a protective atmosphere of anhydrous HCl and Ar. A subsequent growth was done by the zone melting technique. The hydrated chloride had prepared from dissolution of the oxide Pr6O11 in hydrochloric acid. The grown crystals had characterized fluorescence and x-ray diffraction measurements. (Author)

Apresenta-se um metodo eficiente para o crescimento de monocristais de PrCl3, de boa qualidade optica. O metodo consiste na desidratacao cuidadosa do cloreto hidratado, PrCl3. 7H2O, sob uma atmosfera protetora de HCl anidro e Ar, e no subsequente crescimento pela tecnica de fusao por zona. O cloreto hidratado foi preparado a partir do oxido, Pr6O11, pela sua dissolucao em acido cloridrico. O cristal crescido foi caracterizado atraves de medidas de fluorescencia e de difracao de raios-X. (Autor)Original Title
