Aerosol-assisted CVD method for the synthesis of solid particles of t-YSZ-Fe3O4

This work details the production of solid composite particles by the aerosol-assisted chemical vapor deposition method. With this method it is feasible to produce at low temperature (450 degrees C) the tetragonal phase of zirconium oxide stabilizing it with yttrium oxide (YSZ) and cubic iron oxide (Fe3O4) at the same time. The particles have a solid morphology in which both metal oxides coexist without mixing. The average size of the obtained particles is 329 +/- 81 nm, moreover, each particle is formed by thousands of crystallites of size 2 +/- 0.5 nm. The formation of solid structures is due to the amount of Zr and Y found in each particle. These particles can be applied as reinforcements of metallic structures. center dot A simple and low-cost method for producing composite particles to be applied as reinforcing agents for metal structures. center dot The particles are formed by two phases of tetragonal yttria-stabilized zirconia (t-YSZ) and cubic Fe3O4, which was synthesized following a one-step process via the aerosol-assisted chemical vapor deposition method (AACVD). center dot The tetragonal phase of ZrO2 is obtained at 450 degrees C stabilizing it with similar to 3.8% of yttrium oxide.
