Abstract

L'INVENTION CONCERNE UN PROCEDE DE FABRICATION D'OBJETS CERAMIQUES FRITTES. ELLE SE RAPPORTE A UN PROCEDE QUI COMPREND LE MELANGE D'UNE MATIERE CERAMIQUE PARTICULAIRE, NOTAMMENT DU CARBURE DE SILICIUM, D'UNE SOURCE DE CARBONE, AVANTAGEUSEMENT UN ALCOOL, EN QUANTITE COMPRISE ENTRE 1 ET 4 DU POIDS DE LA MATIERE CERAMIQUE ET D'UN ADJUVANT LIQUIDE DE FRITTAGE, FORME PAR UNE SOLUTION DE HBO OU BO DANS DE L'EAU OU UN ALCOOL, CET ADJUVANT DE FRITTAGE ETANT DE PREFERENCE PRESENT EN QUANTITE COMPRISE ENTRE ENVIRON 0,3 ET 5,0 EN POIDS DE BORE PAR RAPPORT A LA MATIERE CERAMIQUE. LE PROCEDE COMPREND AUSSI LA MISE DU MELANGE A LA FORME D'UN OBJET PUIS SON FRITTAGE. APPLICATION A LA FABRICATION D'OBJETS CERAMIQUES POUR APPLICATIONS INDUSTRIELLES.THE INVENTION RELATES TO A PROCESS FOR MANUFACTURING FRIED CERAMIC OBJECTS. IT RELATES TO A PROCESS WHICH INCLUDES THE MIXTURE OF A PARTICULAR CERAMIC MATERIAL, IN PARTICULAR SILICON CARBIDE, A SOURCE OF CARBON, ADVANTAGEOUSLY AN ALCOHOL, IN QUANTITY BETWEEN 1 AND 4 OF THE WEIGHT OF THE CERAMIC MATERIAL AND OF ' A LIQUID SINTERING ADJUVANT, FORMED BY A SOLUTION OF HBO OR BO IN WATER OR AN ALCOHOL, THIS SINTERING ADJUVANT PREFERABLY PRESENT IN QUANTITY BETWEEN APPROXIMATELY 0.3 AND 5.0 BY WEIGHT OF BORON IN RELATION TO THE CERAMIC MATERIAL. THE PROCESS ALSO INCLUDES PUTTING THE MIXTURE INTO THE FORM OF AN OBJECT THEN ITS SINTERING. APPLICATION TO THE MANUFACTURING OF CERAMIC OBJECTS FOR INDUSTRIAL APPLICATIONS.
