Abstract

Inventia se refera la un procedeu de obtinere a unor ferite spinelice de mangan- zinc cu adaosuri de titan, care sînt utilizate ca miezuri în transformatoare de putere cu aplicatii în electronica industriala si electronica bunurilor de consum, prin efectuarea omogenizarii unui amestec de materii prime: oxid de fier, titan, mangan si zinc timp de 16...20 h în proportii de 53...56% mol. Fe indice 2 O indice 3, 1,3% mol TiO indice 2, 28...35% mol. MnO si 12...18% mol. ZnO, presinterizarea materialului la temperaturi cuprinse între 900 si 1100 degree C, macinare, timp de 16...20 h pîna la obtinerea unei suprafete specifice de 2,5...3 m exponent 2 /g si sinterizarea la 1300+1350 degree C în atmosfera aer si racirea lenta în atmosfera cu continut descrescator de oxigen.The invention relates to a process for the production of manganese-zinc spinel ferrite titanium additions which are used as cores in power transformers with applications in industrial electronics and electronics of consumer goods by performing homogenization of a mixture of raw materials: iron oxide, titanium, manganese and zinc for 16 ... 20 hours in proportions of 53 ... 56 mol%. Fe Index 2 About Index 3, 1.3% Mol TiO Index 2, 28 ... 35% Mol. MnO of 12-18 mol%. ZnO, presinterization of the material at temperatures between 900 and 1100 degrees C, grinding for 16 ... 20 h until a specific surface of 2.5 ... 3 m exponent 2 / g and sintering at 1300 + 1350 degree C in the air atmosphere and slow cooling in the atmosphere with decreasing oxygen content.
