SYNTHESIS OF AL2O3-NI COMPOSITE POWDERS BY CO-PRECIPITATION METHOD
The synthesis of micro-sized, uniformly distributed Al2O3-15Vol% Ni powders were studied through three step co-precipitation of hydroxides mixtures from proper solution, calcination at air atmosphere and final step of calcined powders in a carbon bed. Al and Ni hydroxide and amorphous phase were first obtained from their salt’s solutions through chemical co-precipitation method by adjusti...
متن کاملSintering of Al2O3–Ceo2nanopowder Prepared by Co-Precipitation Method
In the present work, Al2O3-CeO2 composite nanopowders were synthesized via co-precipitation method. The sinterability of the synthesized powders was investigated. The results showed that the transformation of transition phases of alumina to α-Al2O3 takes place at 1200 °C. TEM images showed that the powders was composed of nanoparticles in the range of 30−70 nm. The densification of composites s...
متن کاملCo-precipitation Synthesis of Zinc Oxide (ZnO) Nanoparticles by Zinc Nitrate Precursor
Nanostructured zinc oxide (ZnO) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. ZnO nanoparticles were synthesized by co-precipitation method. ZnO nanoparticles were synthesized using Zn(NO3)3 and K2CO3 precursors. The structure of the obtained product was confirmed by the powder X-ray diffraction (XRD) anal...

متن کاملA comparative study on the dispersion of CuO-ZnO-Al2O3 nanoparticles over HZSM-5 via batch co-precipitation, semibatch co- precipitation and combined co-precipitation-ultrasound methods
A series of CuO-ZnO-Al2O3 nanoparticles over HZSM-5 were successfully prepared using different methods of batch co-precipitation, semibatch co-precipitation and combined co-precipitation-ultrasound. Nitrates of copper, zinc and aluminum were used as precursors, while Na-ZSM-5 was employed as composite support and sodium carbonate was used as precipitant agent. The effects of preparation methods...
