Effect of sintering temperature on structural property of X-type barium-zinc hexaferrites

Abstract

X-type Barium-Zinc hexaferrite powder with chemical composition Ba 2 Zn 2 Fe 28 O 46 has been prepared using citrate gel auto combustion technique. The combusted powder waspre-heated at 550 °C for 4 hours followed by final calcinations of 1100 °C and 1250 °C for 5 hoursrespectively. Prepared hexaferrite samples were characterizedusingdifferent instrumental techniques such as FTIR and XRD. XRD analysis of the sample calcined at 1250 °C revealed formation of mono phase of X-type hexaferrite; while the sample calcined at 1100 °C shows multiphases of M, W and X-type hexaferrites. FTIR spectra of both samples show stretching of metal-oxide bands.

“…The major utilization of hexaferrites is in the production of permanent magnets, as well as a wide range of applications including magnetic recording and electrical devices operating in the GHz frequency range. [1][2][3][4][5][6] The employment of hexaferrites in a plethora of magnetic material applications was further encouraged by their favourable properties, chemical stability, relatively high operating temperature, and cost effectiveness. [7][8][9][10][11][12] The various members of the hexagonal ferrite family (M-, Y-, W-, Z-, X-, and U-type) exhibit different magnetic properties, which facilitated their potential use for a variety of applications.…”
