Abstract

The present invention relates to a method for manufacturing Y-type ferrite, and to Y-type ferrite manufactured by same. The method for manufacturing Y-type ferrite according to the present invention comprises a heat treatment step performed at least once, wherein said heat treatment step includes a primary heat treatment step performed at a temperature of 300°C to 500°C, and a secondary heat treatment step performed at a temperature of 1100°C to 1250°C. The method of the present invention is capable of manufacturing Y-type ferrite with a low permittivity, a high magnetic permeability, a low dielectric loss, and a low permeation loss, simply by controlling the heat treatment temperature without substituting a portion of initial materials or without using any additives. Therefore, the Y-type ferrite of the present invention can be used as an element for high frequency (3GHz or lower) devices, and processes for manufacturing the Y-type ferrite can be simplified, and the costs of manufacturing Y-type ferrite can be reduced.
