Изобретение относитс к области порошковой металлургии, в частности к изготовлению ферритов с пр моугольной петлей гистерезиса, широко примен емых в логических и запоминающих устройствах.The invention relates to the field of powder metallurgy, in particular to the manufacture of ferrites with a rectangular hysteresis loop, widely used in logic and storage devices.
Известен способ приготовлени , ферритовой шихты, заключающийс в том, что смесь 1юрошкообразных окислов и солей металлов подвергают вибропомолу в окислительной атмосфере, нагрева в процессе помола смесь до 250500°С 1.The known method of preparation of the ferrite mixture, which consists in the fact that a mixture of 1-powder oxides and metal salts is vibrated in an oxidizing atmosphere, heating the mixture to 250,500 ° C 1 during grinding.
Недостатком известно способа вл етс низка производительность.The disadvantage of the known method is low productivity.
Целью изобретени вл етс повышение производительности процесса.,5The aim of the invention is to increase the productivity of the process., 5
Дл достиже1ш поставленной цели предложен способ приготовлени ферритовой шихты,In order to achieve this goal, a method has been proposed for the preparation of ferrite charge,
включающий вибропомол смеси пороижообразных окислов и солей в окислительной атмосфере при нагреве, который отличаетс от известного тем, что нагрев ведут при 505-800°С. Пример осуществлегш способа. Смесь исходных компонентов,%: FejOs85,4including vibromoil of a mixture of porous oxides and salts in an oxidizing atmosphere during heating, which differs from the known fact in that it is heated at 505-800 ° C. An example of a method. The mixture of initial components,%: FejOs85,4

подвергалась вибропомолу в экспериментальной установке при различных температурах.was subjected to vibratory milling in the experimental setup at different temperatures.
В таблице приведет данные, характеризующие зависимость удельной намагниченности шихты , измеренной в гс-см /г, от температуры и времени помола.The table will give data characterizing the dependence of the specific magnetization of the mixture, measured in gf-cm / g, on the temperature and time of grinding.
