ترجمة الملخص

The aim of this research project was to synthesisthe following mixed oxide Zn2-x(Tia:Snb)1-xFe2xO4viasolid state process and study of their crystal structure and characteristics mainly by X-ray powder diffraction (XRPD) Fourier transform infra-red spectroscopy (IR) and theoretical and practical density study. All samples were prepared carefully and then were burned at 1000 oC temperature after experimentation and article review. The final powders obtained was different and their properties was influenced by themolar ratio Ti:Sn,precursors and calcination time . The mixed oxide was obtained at 1000oC temperatureand with different Ti:Sn molarratio, and a strong similarity between their x-ray patterns was noticed with slight differences.Solid stateprocess was chosen because of its advantages over other preparation methods due to the fact that the formation of the oxide is almost garneted with this traditional process, also powders synthesized by this process obtain desirable propertiesto beused on many industrial levels as presented in earlier studies done on oxides produced by this process.All resulting samples had a brown color due to presence of Fe with a slight difference in color in some samples, the color change can be traced to theTi:Snmolar ratio. The mixed oxides wereformed at different Tin and Titanium ratios with a constant percentage of Zinc and Iron calculated at the early experimentation.XRPD patterns for all samples indicated the formation of the mixed oxide and the absence of main peaks of the precursors. Crystal constant (a) and volume were calculated and the results showed the oxide has a cubic structure and both crystal constant (a) and volume were affected by the change in molar ratio.Density and FT-IR study of all samples proved the result obtained via XRPD patterns and their for we can conclude that the desired mixed oxide was formed with good results at the given ratios and temperature.
