ANALISIS STRUKTUR KRISTAL MATERIAL BARIUM HEKSAFERRIT BaFe12-x(CoTi0.5Mn0.5)x/2O19

Abstract

Barium hexaferrite with hexagonal molecular BaFe₁₂O₁₉ is one of the magnetic materials that widely used for research, about improving the quality of material corresponding the application. BaFe₁₂O₁₉ has high H_C (magnetic saturation), good chemical stability, high T_C (Curie temperature) and corrosion resistant. Synthesis material BaFe_12-x(CoTi_0.5Mn_0.5)_x/2O₁₉, with x=0 and x=1, made through smoothing BaCO₃, Fe₂O₃, Co₃O₄, TiO₂, and MnCO₃ using High Energy Ball Mill for 1 hour by using wet milling method. Then calcinating at temperature of 750°C for 3 hours and sintering at temperature 1100°C for 6 hours. Expected in this material may be formed phases can be identified and analyzed qualitatively and quantitatively using X-Ray Diffractometer (XRD) to identify the crystal structure of the materials and processed using High-Score Plus application. From the XRD chart, known that the substitution ion Mn, Co and Ti has been done. The value of lattice parameter is a = b =5.88 Ã…, and c = 23.24 Ã….
