摘要

An experiment was carried out to investigate the influence of CaCO₃ and SiO₂ additives on the magnetic and physical properties of M-type Sr ferrites by changing experimental parameters such as the additive composition and Ca/Si ratio. Specimens were prepared by conventional ceramic techniques. It was found that the magnetic properties (B_r = 4.42 kG, iH_c = 3.32 kOe and (BH)_max = 4.863 MGOe) were considerably improved upon adding CaCO₃ = 1.1% and SiO₂ = 0.4 wt% together with Co₃O₄, and the mechanical properties thereof were acceptable for motor applications. It was revealed that CaCO₃ and SiO₂ additives led to an upswing in the magnetic properties via the enhancement of uniform grain growth, particle alignment, and the densification of Sr ferrite.
