Abstract

The effects of Al2O3 addition on the change of structure and magnetic properties change of permanent magnets BaO6(Fe2O3) has been made and analized by bulk metallurgy processes to made strength materials on Technology Application. The material structure was determined by Xray diffraction which gave information about the phase formed and grain boundary. The study of samples homogenity by Photo micro method with 500 times exaggerated, meanwhile the density and porosity of material determined by theoretical calculation and experiment results. The extrinsic magnetic properties which consists of remanen, coersivity and density of maximum energy product of the materials are obtained by analyzed the demagnetization curve produced by B-H Tracer equipment. The best quality of material is obtained wich 0.5% Al2O3 additive and 360 minutes recovery which yield 4,767 gr/cm3 density or 10,581% porosity, 102 kA/m coersivity and 5.1 kJ/m3 density of maximum energy product.
