PURPOSE: A preparation method of multipurpose magnetized ceramic powder having active function to human body, deodorization, sterilization and far-infrared emission is provided by magnetizing sintered ceramic powder comprising ceramic powder having magnetic force, tourmaline and sepiolite. CONSTITUTION: The method comprises the steps of: mixing 60-100pts.wt. of sintered ceramic powder, 10-40pts.wt. of tourmaline and 10-20pts.wt. of sepiolite; pressing; sintering at 600-690deg.C for 1-5hrs.; grinding to 200-500 mesh of size; magnetizing with 1200-1400gauss. The above sintered ceramic powder is prepared by mixing 65wt.% of mineral stone(called macbansuk) having a size of 250-350mesh, 35wt.% of sericite and adding water; aging for 3days, then forming; sintering at 720-790deg.C for 4-6hrs.; grinding to 230-550mesh of size; magnetizing with 800-1200gauss.
