Residual stress was measured in sintered and heat-treated Fe2TiO5 samples with various grain sizes. The influence of texturing was assessed by comparing the residual stress states of samples having randomly oriented grains and highly oriented grains produced through magnetically assisted processing. The residual stress was measured with x-ray diffraction using Cr Ka radiation. Due to the signif...

Fe2TiO5 was synthesized via nonhydrolytic sol-gel method at 600?C. The effects of iron sources on the synthesis were investigated. It demonstrated that Fe-O-Ti bonds will not be formed in xerogels prepared by taking FeCl3 as source because it is strong Lewis acid and induces homocondensation. using Fe(OC2H5)3 FeOH(CH3COO)2 sources. However, hydroxyl group easily leads to homocondensation partic...

Ilmenite is a vital raw material for the production of metal titanium and titanium-containing materials. In this paper, microstructure chemical transformation natural ilmenite in air atmosphere were investigated by analysis XRF, X-ray diffractometer, SEM-EDS. Results showed that untreated had three layers after oxidation at 800 °C 60 min, which Fe2O3, TiO2 inside mixture layer Fe2O3 turn. Subse...
