Abstract
LA PRESENTE INVENTION CONCERNE UN PROCEDE DE FABRICATION D'UN MOULE REFRACTAIRE IMPREGNE DE TUNGSTENE AYANT UNE FAIBLE REACTIVITE ET LE MOULE AINSI OBTENU. LE PROCEDE CONSISTE A IMPREGNER UN MOULE-CARAPACE REFRACTAIRE HABITUEL PAR UNE SOLUTION AQUEUSE D'ACIDE TUNGSTIQUE DANS DE L'HYDROXYDE D'AMMONIUM. ON SECHE LE MOULE SATURE ET ON LE CUIT POUR TRANSFORMER LE COMPOSE DE TUNGSTENE EN TUNGSTENE METALLIQUE OU OXYDE DE TUNGSTENE. LE PROCEDE PEUT ETRE REPETE PLUSIEURS FOIS POUR OBTENIR LA CONCENTRATION EN TUNGSTENE SOUHAITEE. L'INVENTION EST PAR EXEMPLE UTILISABLE POUR LE MOULAGE DE METAUX REFRACTAIRES TELS QUE DU TITANE.
