    摘要

    Microstructural dependence of magnetic permeability and magnetic loss of Ni-Zn ferrites sintered from slip cast colloidally precipitated ultrafine particles was investigated. A low-loss Ni-Zn ferrite (tan δ/μ0 = 4.92 x 10-5 at 1 MHz) having nearly maximum attainable density, fairly uniform and small grain size, and no significant zinc loss, was prepared by sintering at 1100°C. There was considerable discrepancy in the permeability-grain size relation between $$1100°C sintered ferrites and > 1100°C sintered ferrites. The zinc loss and intra-granular pores in >1100°C sintered ferrites may explain this discrepancy.
