Abstract
POUDRE METALLIQUE DONT LES PARTICULES COMPRENNENT UN NOYAU CONTENANT UNE PROPORTION MINEURE D'ARGENT ET UNE COUCHE PERIPHERIQUE D'UN ALLIAGE D'ARGENT ET D'ETAIN. L'USAGE D'UN NOYAU COMPORTANT UNE FAIBLE PROPORTION D'ARGENT PERMET A L'ENSEMBLE DES PARTICULES D'AVOIR UN CONTENU EN ARGENT FAIBLE. CES POUDRES PEUVENT ETRE UTILISEES POUR FORMER DES AMALGAMES DENTAIRES. LEUR PROCEDE DE PREPARATION COMPORTE AVANTAGEUSEMENT L'ENTRAINEMENT DES PARTICULESA DANS UN COURANT DE GAZ PORTEUR INERTE SOUS PRESSION (JET18) QUI TRAVERSE UNE ZONE DE CHAUFFAGE (FLAMME16) PUIS LEUR REFROIDISSEMENT (LIQUIDE REFRIGERANT20).
