Abstract

DANS UN PROCEDE POUR LA PREPARATION D'UN ALUMINATE LUMINESCENT CONTENANT DE L'ALUMINIUM ET AU MOINS L'UN DES METAUX YTTRIUM ET DES ELEMENTS DE LA SERIE DES LANTHANES, LES METAUX COMPOSANTS DE L'ALUMINATE SONT COPRECIPITES A PARTIR DE SOLUTIONS AQUEUSES DE SELS DE CES METAUX PAR REUNION DE CES SELS AVEC UN PRECIPITANT CONTENANT DU BIOXYDE DE CARBONE ET DE L'AMMONIAQUE DANS UNE QUANTITE DE 1 A 3 MOLE(S) PAR MOLE DE BIOXYDE DE CARBONE. ON UTILISE UNE QUANTITE DU PRECIPITANT TELLE QUE LE RAPPORT MOLAIRE ENTRE LE CARBONE DANS LE PRECIPITANT ET LA SOMME DES METAUX DANS LES SELS PRESENTE UNE VALEUR COMPRISE ENTRE 1 ET 10, AVEC LA RESERVE DE CHOISIR POUR CE RAPPORT DANS LADITE GAMME UNE VALEUR PLUS ELEVEE A MESURE QUE LA GROSSEUR MOYENNE REQUISE DES GRAINS DU PRECIPITANT EST PLUS GRANDE. LE PRECIPITAT AINSI OBTENU EST FINALEMENT CHAUFFE A TEMPERATURE ELEVEE. APPLICATION: SUBSTANCES LUMINESCENTES.
