Abstract
An object of the present invention is to provide ferrite particles for a filtering medium excellent in filtration ability having a small apparent density, capable of various properties maintained in the controllable state and filling a specified volume with a small amount, and a filtering medium made from the ferrite particles. In order to achieve the object, ferrite particles provided an outer shell structure containing Ti oxide for a filtering medium, and a filtering medium made from the ferrite particles are employed.
Claims9
A particle comprising a core and an outer shell, the outer shell comprising a titanium oxide, and the core comprising ferrite;
- wherein an apparent density of the core is smaller than an apparent density of the outer shell.
