Hydrothermal Reaction Sintering of Permalloy-Iron Oxide Composite

Improve Synthesis of Iron Oxide Nanorode with Hydrothermal Method

Maghemite and magnetite nanoparticles and nanorode are now losing interests in the field of nanobiotechnology and pharmaceutical for their applications. This paper reports on a hydrothermal process for the synthesis of Fe2 O3 in the γ-phases nanorodes, when the hydrothermal temperature was 100 ̊ C. The uniqueness of the method lies in the use of ferrous ammonium sulphate, hexamine was added as t...

Sintering properties of zirconia-based ceramic composite

This study examines the effects of different ZrB2 content on various mechanical properties and electrical conductivity of ZrB2/Y-TZP composite. Composites with ZrB2 content of up to 20 wt-% were particularly beneficial at the lower sintering temperature range by achieving greater densification and better hardness than Y-TZP monolith. In contrast to the trends estimated from rule of mixture, the...

Sintering of Fine Oxide Powders: II, Sintering Mechanisms

Conventional and new sintering mechanisms have been porous compacts is well-known in the ceramic literature. However, several reports have been presented recently that investigated using fine powders of CeO2 and Y2O3 of excellent sinterability. We have verified the validity of Herring’s show that particle/grain size can remain essentially constant up to a density of 92%, and such a resistance t...

The Comparison of MgO and TiO2 Additives Role on Sintering Behavior and Microstructures of Reaction-Sintered Alumina-Zirconia-Mullite Composite

Alumina-Mullite-Zirconia ceramic composites were prepared by reaction sintering of alumina, zircon mixture and the sintering aids of magnesia and titania at temperatures of 1400 and 1600 C for 2 hours. The development of different phases and microstructures of the composites were analysed to assess the relative influence of the additives on the formation of alumina-zirconia-mullite compos...
