Influence of MnO2 on the sintering behavior and magnetic properties of NiFe2O4 ferrite ceramics

Resistance-temperature characteristics of a new high-temperature thermistor ceramics of Mn-doping Ba–Ca–Zr–Ti–O system

“…The two main characteristic peaks Mn 2p 3/2 and Mn 2p 1/2 are located at 641.7 ev and 653.5 ev, respectively, owning to spin-orbit coupling, the split between 2p 3/2 and 2p 1/2 is close to 11 ev, and the results are consistent with the reference [40]. Under different doping conditions (x = 0.010, x = 0.015, and x = 0.100), the full width at half maximum (FWHM) of Mn 2p is 0.26, [43], resulting in a variety of valence states [44,45]. Since the Mn 2p 3/2 signal has a high sensitivity to distinguish the valence state and spectrum is selected for fitting and analysis [41,46].…”

Hydrothermal synthesis and characterizations of Ti substituted Mn-ferrites

“…Substitution of magnetic and non-magnetic cations in ferrite materials changes their magnetic and electrical properties [31][32][33]. The changes in physical and chemical properties of ion substituted spinel ferrites arise from the ability of these compounds to distribute the cations between the available A-sites (tetrahedral) and B-sites (octahedral) [34][35][36].…”

The Mechanical Alloying Behavior of Fe2O3 into NiO in the High‐Energy Ball‐Milling Process

“…Researches are available on synthesizing of NiFe 2 O 4 ceramics by sintering of the NiO and Fe 2 O 3 powders [16,17]. But few studies have been reported about the effects of highenergy ball-milling on the microstructure of these two powders, especially its effect on the subsequent synthesizing reaction.…”
