Mixed-Valence Defect Ferrites : a New Family of Fine Powders and Thin Films of Spinel Ferrites

When highly divided spinel fenites become reactive enough with oxygen, to allow the oxidation of the Fe ions at low temperature and of substitute cations too, when these cations are capable of different valence states. We prepared fine particles of spinel ferrites substituted by Mn, Mo, Cu, by "chimie douce", especially from oxalate precursors and used them to reveal and to study the oxido-redu...

Preparation and Ethanol Sensing Behavior of Spinel-type Nanosized Mixed Ferrites Containing Zn

Nanocrystalline Ni1-xZnxFe2O4 (x = 0, 0.2, 0.3 and 0.4) mixed ferrite with cubic spinel structure was successfully prepared by the citrated sol-gel method followed by calcinations at 600 C. Characterization of the materials was performed by XRD. Indirect-heating sensors using as-prepared powders of mixed ferrite as sensitive materials were fabricated on an alumina tube with Au electrodes and Pl...

PRESSURELESS SINTERING OF B4C-NANOTiB2 NANOCOMPOSITE BY ADDITION OF Fe AND Ni AS SINTERING AIDS

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...
