Abstract
Method of manufacturing an annular magnetic core with an external diameter of 2.8 to 4 mm, an internal diameter of at least 0.6 times the external diameter and a height of 1 to 2 mm to be used as a circuit breaker element, to control memories of nuclei, characterized in that a mixture of 14 to 15 mol% of Li2O 6 to 7 mol% NiO, and 77 a 81 mol% de Fe2O3 mixture in which the oxides can be replaced individually by compounds capable of transforming into these oxides during heating, is pre-sintered at a temperature between 600 and 750º C, the product thus obtained is refined and then granulated and compressed in the desired form, the body The tablet is heated to a temperature of 1370º C to 1400º C within a maximum of 16 minutes, said temperature being maintained for 5 to 10 minutes, and the reaction product is subsequently cooled to a temperature of 940 to 960º C within a time period of 70 minutes. to 90 minutes and finally it is tempered by direct contact with air at room temperature.
