Latest Patents

Masao Tsuzaki holds a patent for a method of producing composite oxides for use as starting materials. This method involves creating an oxide that serves as a precursor for soft ferrites, primarily composed of iron, zinc, and other selected metals. The process includes roasting chlorides of metals other than zinc to produce a composite oxide while adding zinc oxide during the roasting phase. This technique ensures a high yield of zinc oxide without relying on zinc chloride, which has a high vapor pressure. The resulting oxide has the desired metal ratios and contains spinel ferrites with uniformly dispersed zinc oxide. This innovation allows for the omission of a calcination step and a powder mixing step in the ferrite production process, leading to high-quality ferrites obtained through direct sintering.
