The high-Tc Y1-xNixBa2Cu3O7-δ samples doped by Ni for Y atom, with x=0, 0.002, 0.004, 0.006 and 0.01 were synthesized by the standard solid-state reaction method. The XRD diffraction of samples showed no impurity phase in all samples. Magnetic susceptibility of the samples under two different magnetic fields of 0.8 and 400 A/m was measured. The results showed that by increasing nickel element t...
In this paper, LiMn2O4 spinel cathode materials have been successfully synthesized by solid-state reaction. Surface of these particles modified by nanocoating of LiFePO4. Synthesized products were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDX). The results of electrochemical tests showed that charge/discharge ca...
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...
A thermoanalytical (TGA/DSC) and diffractometric (XRD) study has been performed on the solid state reaction system L i 2 C 0 3 F e 2 0 3 in the xLi range 0.10-^0.50. A detailed analysis of the results shows that the data are in agreement with a reaction model where the carbonate decomposition is regulated by the formation of both L i F e 0 2 and L i F e 5 0 8 , and the relative amount of the tw...
Kinetic data for the solid-state reaction of sulfadiazine and acetylsalicylic acid are presented. A compaction method was used to observe the influence of applied pressure, particle size, and temperature on the reaction rate.
