| titleOfInvention | Manufacturing method of soft magnetic ferrite |
| abstract | The present invention relates to a method of manufacturing a soft magnetic ferrite used in a chip inductor, which is a kind of surface mount component. The purpose of the present invention is to provide a method for producing soft magnetic ferrite having electromagnetic characteristics of magnetic permeability: 100 to 120 and Q: 200 to 240 at a melting point of 3 MHz at 950 ° C as well as lower than the melting point.n n n The present invention for achieving the above object of the soft magnetic ferrite comprising crushing, calcining, crushing, forming and firing the starting material composed of iron oxide (Fe 2 O 3 ) and metal oxide (MO) as needed In the production method, the starting material is composed of mol%, Fe 2 O 3 : 49.0-49.6%, NiO: 20.0-20.5%, ZnO: 20.0-20.5%, and CuO: 10.0-10.5%, or starting The summary is to provide a method for producing a soft magnetic ferrite comprising the material as described above and adding CuO: 0.5 to 3.0% by weight and SiO 2 : 500 to 1000 ppm alone or in combination. |
