摘要：In this paper, microwave sintering (MS) technology has been applied in the preparation of ferromagnetic-ferroelectric composites. The Ni0.3Zn0.6Cu0.1Fe2O4(NiCuZn) + 15%(wt.)CaCu3Ti4O12(CCTO) composites have been fabricated by both MS technology and conventional sintering (CS) technology, respectively. We found that the fabricating time and sintering temperature were 22 h and 1100 degrees C for the CS process and 2 h and 900 degrees C for the MS process. Experiments show that MS treated NiCuZn-CCTO composites possess both excellent ferromagnetic and ferroelectric properties. For the composites of NiCuZn+15% CCTO, the real part of permittivity is larger than 360 when the frequency is lower than 1.2 MHz, and the real part of dielectric constant is larger than 2000 when the frequency is lower than 1.0 MHz. Our results indicate that the MS method is a potential important technique in LTCC technology.
