Cobalt oxide nanoparticles by solid-state thermal decomposition: Synthesis and characterization

In this study, mononuclear octahedral cobalt(III) Schiff base complex [CoL3], L = (5-bromo-2-hydroxybenzyl-2-furylmethyl)imine, was synthesized from the reaction of Co(NO3)2•6H2O and the Schiff base ligand L in methanol as solvent. It used as a new precursor to prepare spinel type cobalt oxide nanoparticles by a facile solid-state thermal decomposition. Controlling the temperature and time, Co3...

Kinetics of the Solid State Reaction between CuO

The solid state reaction of CUWO4-2 formation from CuO and WO3 was studied by the contact method in air and nitrogen. The results showed that the reaction is governed by the diffusion of the W 6 + and 0 2 _ ions and that the rate determining step is the diffusion of oxygen ions in the reaction product. This is in agreement with the defect structure of copper tungstate, an n-type semiconductor w...

Synthesis & Characterization of CaB4O7 Powder by Solid-State Reaction

The synthesis of calcium tetraborate was investigated in a temperature ranging from 800℃ to 900℃ using the solid-state reaction method. The synthesis was done using ammonium tetraborate tetrahydrate as the source of boron. At temperatures of 800 ℃ and 880 ℃, the mixed phases from different compounds were formed. At the optimum temperature of 840℃, the mixed phase was only composed of meta and t...

SOLID STATE IOlllCS Mixed conducting yttrium-barium-cobalt-oxide for high oxygen permeation

Yttrium-barium-cobalt-oxide (YBC), especially with low Y content, has been prepared. Oxygen permeation in these materials is very high at moderate temperature. The materials Yo.osBaCoo.95Oa_6 and Yo.~oBao.9oCoO3_6 consisted of a BaCoO3_6like main phase and some minor phases. For the Yo.osBaCoo.9503_6 material these minor phases were not exceeding 10 vol%. Yo.osBaCoo.9503_6 had the highest oxyge...
