Issue Date: | Feb-2012 | Publisher: | Elsevier | Citation: | Materials Research Bulletin 47(2): 285-289 (2012) | Abstract: | This work describes a wet-processing route based on spray-freezing and subsequent lyophilization designed to obtain nanostructured ceramic/metal powders. Starting from the ceramic powder and the corresponding metal salt, a water-based suspension is sprayed on liquid nitrogen. The frozen powders are subsequently freeze-dried, calcined and reduced. The material was analyzed using X-ray diffraction analysis at all stages. High resolution transmission electron microscopy studies showed a uniform distribution of metal nanoparticles on the ceramic grain surfaces, good interfaces and high crystallinity, with an average metal particle size in the nanometric range. | Description: | 5 páginas, 8 figuras, 1 tabla.-- El pdf del artículo es el manuscrito de autor. | Publisher version (URL): | http://dx.doi.org/10.1016/j.materresbull.2011.11.027 | URI: | http://hdl.handle.net/10261/48247 | DOI: | 10.1016/j.materresbull.2011.11.027 | ISSN: | 0025-5408 |
