Latest Patents

Katsunobu Okutani 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 heating step raises the temperature from room temperature to 600°C within a period of 30 minutes to 5 hours. The second heating step increases the temperature from 600°C to the sintering temperature, maintaining that temperature 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 Mn-Zn ferrites.
