Paper Title:
Effect of the Combination of HTR and NTR Processes on the Magnetic Properties of Strontium Hexaferrite
  Abstract

Hydrogen treatment and re-calcination (HTR) and nitrogen treatment and re-calcination (NTR) processes have marked effects on enhancement of the magnetic properties , particularly coercivity, of the strontium hexaferrite powder synthesized conventionally. This improvement is mainly attributed to finer structure obtaining after gas treatment. In this work, the effects of different combinations of these processes on the powder and bulk magnetic properties have been studied by using VSM and Permeameter. XRD and SEM techniques have also been used for characterization of the processes.
