Abstract

This paper describes a new method for measuring the magnetic
properties of hexagonal Barium ferrite using approximation method
(APM) theory. The sample was prepared by recycling the waste steel
product from Malaysian steel factories. Using a Curie temperature
separation technique, the wustite, FeO contained in the millscale
was separated by this new technique using de-ionized water at 90°CI
100°C in the presence of IT external field. The wustite was then
oxidized in the air at 400°C/500°C/600°C for 10 hours. An XRD
phase analysis showed that a very high percentage of Fe20 3 was
present in the final powder preparation. A conventional processing
method was then done to prepare hexagonal BaFe'20'9 pallet shaped
samples. Analysis of samples was done on grain size, saturation
magnetization, coercive force and remanence. The magnetic
properties were measured using approximation method (APM) theory.
The high remanence 20000e, 20000e saturation magnetisation and
15000e coercive force of sample derived from millscale shows that
this technique used has a high percentage for magnetic properties
measurement in the future.
