説明

The degree of orientation, f and f′, for anisotropic barium ferrite sintered at 800°∼1300°C were determined from X-ray powder patterns following the procedures of Lotgering and Gillam et al. Comparing their relationship to the magnetic properties, it was proved in the scope of the present experiment that the correction of Lotgering’s f values after Gillam et al. did not give a practical improvement and Lotgering’s method is reasonably applicable to the industrial inspection. Br\varparallel⁄Bs and Br\varparallel⁄(Br\varparallel+Br⊥) had the closest relationship to the degree of orientation among various magnetic properties, where Br\varparallel and Br⊥ indicate the residual inductions parallel and perpendicular, respectively, to the magnetic field applied during the pressing process.<BR>Besides these ratios, the fullness factor of the B-H curve and Br were measured, and it was found that they increased monotonically with the increase of f or f′. On the other hand, the fullness factor of the I-H curve and (BH)max show maxima in the neighbourhood of f=50%.
