چکیده
The structure of the high-temperature scheelite-type polymorph of cerium niobium tetraoxide, CeNbO(4), has been determined using time-of-flight neutron powder diffraction data collected both in situ at 1073 K in air and in vacuo. In both cases, the structure was found to be tetragonal, with I4(1)/a symmetry and without any significant deviation from the stoichiometric composition.

A powder mixtures of 18.72% wt, 17.67% wt Al2O3 and 63.6% wt zircon were prepared and milled in a planetary ball milled for one up to 10 hours in presence of air. After removal Iron impurity from as-milled samples, they were isothermally heated in temperature range of 1300-1450 0C for one hour in an air atmosphere. After cooling the samples, they were studied using XRD analyses. The XRD and PSA...
متن کاملEffect of Amorphous Silica Addition on Martensitic Phase Transformation of Zirconia and Investigation of its Tetragonal Structure Stability Mechanisms
This work is focused on the effect of amorphous SiO2 addition on the phase transformation and microstructural evolution of ZrO2 particles. Considering the structural similarities between the amorphous ZrO2 and its tetragonal structure, XRD results showed initial nucleation of metastable tetragonal ZrO2 from its amorphous matrix upon heat treatment. This metastable phase is unstable in pure ZrO2...

Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...
متن کاملExperimental study and application of computational fluid dynamics on the prediction of air velocity and temperature in a ventilated chamber
The shape of the air flow in the interior is heavily influenced by the air distribution system and the way air enters and exits. By numerically simulating flow by computational fluid dynamics, one can determine the flow pattern and temperature distribution and, with the help of the results, provide an optimal design of the air conditioning system. In this study, a chamber was first constructed ...
