Method for producing Mn-Zn ferrites

摘要

A method for sintering Mn-Zn ferrite green compacts is provided which includes a first heating step of raising the temperature from room temperature to 600 DEG C. within a period from 30 minutes to 5 hours, a second heating step of raising the temperature from 600 DEG C. to the sintering temperature and holding the sintering temperature until the start of cooling within a period shorter than 10 hours, and a cooling step of lowering the temperature to 150 DEG C. within a period longer than 3 hours, with the total period of the three steps being shorter than 20 hours. This method permits the efficient production in a short time of Mn-Zn ferrites having good magnetic properties.
