α-fe2o3 (hematite) is the most stable iron oxide under ambient conditions. this transition metal oxide has been extensively investigated because it has unique electrical and catalytic properties. in this report, a novel microwave method for preparation of α-fe2o3 nanoparticles has been developed. the process contained two steps: first, precursor were obtained from a mixed solution of 50 ml of 0...

aluminophosphate-5 (alpo4-5) nano-pore zeolite was synthesized. the effect of alteration in precursor gel preparation on the morphology of zeolite was studied. the effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of alpo4-5 zeolite been studied. a hydrothermal synthesis has been used to produce nano-pore aluminophosphate-5 crystals. the crystals ...

TiO2/ZrO2 nanocomposite was obtained by the sonochemical technique. In this method, two separate gels containing zirconium and titanium were prepared and mixed together. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4. The precursor titanium tetra isopropoxide (TTIP) dissolved in isopropanol. Mixing of Titanium and Zirconium gels was resulted in a yellow TiO2/ZrO2 ...
