Low temperature sintering of iron deficient Z type hexagonal ferrites

High-Curie-Temperature Pb(Zr,Ti)O3 Ceramic Actuator Cofired with Pure Silver Internal Electrodes

“…3) In our other previous studies, LiBiO 2 was adopted as a sintering additive since the low-temperature sintering of Z-type ferrites could be attained with the aid of the additive. 8,9) As a result, a chip inductor with Ag internal electrodes having a high impedance in the GHz region was obtained. Accordingly, LiBiO 2 was added to the unground PZT powder as a sintering additive before grinding to lower Fig.…”

Dual-ion substitution induced high impedance of Co 2 Z hexaferrites for ultra-high frequency applications

“…From Ref. [19], the k value of the ferrite bead with size of 1.6 Â 0.8 Â 0.8 mm 3 is estimated to be 2.1 at 2 GHz. More importantly, the frequency dependence of the impedance value of the dual-ion substitution Z-type ferrite (3Ba 0.52 Sr 0.48 OÁ2CoOÁ 0.025Gd 2 O 3 Á10.775Fe 2 O 3 ) is plotted in Fig.…”

Crystalline phases and magnetic properties of Cu–Bi–Zn co-doped Co2Z ferrites

“…The phase formation temperature of Co 2 Z ferrite prepared using the solid state reaction method is as high as 1250-1300 • C due to its complex structure [5]. The substitution of Cu for Co and Bi for Ba can promote the formation of Z-type ferrite at a low temperature [6]. However, to our best knowledge, there is no study on the effects of Cu-Bi-Z co-doping on the crystalline phase and magnetic property of Co 2 Z ferrite.…”
