The glazo painted on the surface of a ferrite tile contais a ferrite powder of below 40%(v/v), wherein the ferrite tile is manufactured by mixing Fe2O3, NiO and ZnO into a composition of Ni0.3Zn0.7Fe2O4, calcinting the mixed compounds at 900≦̸C for 2 hours, grounding and forming the calcinted powder under the pressure of 450kg/cm2, and sintering it at 1200≦̸C for 2 hours.
