Latest Patents
Fujiwara holds a patent for a method for producing Mn-Zn ferrites. This method involves a three-step sintering process that efficiently produces Mn-Zn ferrites with excellent magnetic properties. The first step raises the temperature from room temperature to 600°C over a period of 30 minutes to 5 hours. The second step involves increasing the temperature to the sintering temperature and maintaining it until cooling begins, all within a period shorter than 10 hours. Finally, the cooling step lowers the temperature to 150°C over a period longer than 3 hours, with the total duration of the three steps being less than 20 hours. This innovative approach allows for the efficient production of high-quality ferrites in a shorter time frame.
