Sintesis Barium Heksaferrit Tipe W Melalui Metode Mechanical alloying
W-type Barium hexaferrite with a crystal structure BaMe2Fe16O27 (Me is a divalent metal) has a good magnetic properties and high value of currie temperature. Ion substitution on W-type Barium Hexaferrite can be improve the properties of W-type Barium Hexaferrite. For this research, substitution Fe by ion Co and Ti with x = 0 and 0.1 by mechanical alloying method will be performed. Mixing of basic materials BaCO3, Fe2O3, Co3O4, and TiO2 by milling process using high energy ball mill in a wet milling condition using toluene for 1 hour followed with calcination and sintering. Then Crystal structure in the sample will be analyzed using XRD (X-Ray Diffraction) with CuKÎ± radiation. The calculation of the phase BaCoTiFe16O27 (x = 0) obtained values of lattice parameters a=b= 5.886 Ã… dan c= 23.236 Ã…, while the phase BaCoTiFe15.8Co0.1Ti0.1O27 (x = 0.1) obtained values of lattice parameters a=b= 5.894 Ã… dan c= 23.257 Ã….
