Abstract

L'INVENTION A POUR BUT LA PRODUCTION DE FERRITE DOUX, DE PERMEABILITE INITIALE VOISINE DE500, UTILISABLES A DES FREQUENCES POUVANT ALLER JUSQU'A500KHZ ET PRESENTANT UNE RESISTIVITE DE 10 A 10000MEGOHM-CM. LE FERRITE SELON L'INVENTION EST UN MATERIAU POLYCRISTALLIN OBTENU A PARTIR D'UN MELANGE DE POUDRES PREALABLEMENT BROYEES, SELON LA FORMULE DE DEPART CI-APRES: LI TI ZN MN FE OB BIMOLE AVEC: A 0,5 (1 T - Z) B 0,5 (5 - 3T - Z - 2M - 5E) OU L'ON A: 0 T 0,08 0,50 Z 0,60 0,005 M 0,035 0,02 E 0,06 ET 0,0015 B 0,05. CES POUDRES SONT FRITTEES AUX ENVIRONS DE 1000C APRES AVOIR ETE EVENTUELLEMENT CHAMOTTEES VERS700C. APPLICATION A LA FABRICATION DE DEFLECTEURS MAGNETIQUES ET DE BAGUES DE DEFLEXION DE TELEVISEURS "COULEUR".THE PURPOSE OF THE INVENTION IS TO PRODUCE SOFT FERRITE, WITH AN INITIAL PERMEABILITY OF NEAR 500, USED AT FREQUENCIES UP TO 500KHZ AND PRESENTING A RESISTIVITY OF 10 TO 10000 MEGOHM-CM. FERRITE ACCORDING TO THE INVENTION IS A POLYCRYSTALLINE MATERIAL OBTAINED FROM A MIXTURE OF PREVIOUSLY GROUND POWDERS, ACCORDING TO THE STARTING FORMULA BELOW: LI TI ZN MN FE OB BIMOLLE WITH: A 0.5 (1 T - Z) B 0.5 (5 - 3T - Z - 2M - 5E) OR ON A: 0 T 0.08 0.50 Z 0.60 0.005 M 0.035 0.02 E 0.06 AND 0.0015 B 0, 05. THESE POWDERS ARE SINTERED AT ABOUT 1000C AFTER HAVING BEEN CHAMOTTED TO 700C. APPLICATION TO THE MANUFACTURING OF MAGNETIC DEFLECTORS AND DEFLECTION RINGS FOR "COLOR" TELEVISIONS.
