Abstract

This study was investigated to fabricate the porcelain materials with high magnetic characteristics. The high characteristics of the magnetic porcelain materials were achieved at the following conditions; powder sizes of isotropic Sr-ferrites with $1{\sim}2\;mm$ and magnetic powder infraction of 30 wt%. The magnetic tea cups with 3-mm-thick at the optimum conditions indicated the high magnetic characteristics such as the surface flux density of 178 G, the remanent flux density of 240 G, and the intrinsic coercivity of 3910 Oe.
