Abstract

The magnetic porcelain materials were studied by using the porcelain materials added Sr-ferrite powders before forming and firing process. For the high magnetic property, the Sr-ferrite magnetic powders with the grain size of 1 ${\mu}m$ were agglomerated the powder size of about 1 mm. The magnetic porcelain with 30 wt% of Sr-ferrite powders indicated the magnetic characteristics such as the remanent flux density of 240 G and the intrinsic coercivity of 3910 Oe, at the firing conditions of $1250^{\circ}C$/1hr in air.
