Ordered coalescence of nanocrystals: a path to strong macroporous nanoceramics
2010 (English)In: Nanotechnology, ISSN 0957-4484, E-ISSN 1361-6528, Vol. 21, no 20, 205602- p.Article in journal (Refereed) Published
A versatile approach for integrating two apparently conflicting physical properties, high porosity and high mechanical strength, in polycrystalline bulks is established and demonstrated for the case of alumina ceramics. Macroporous alumina nanoceramics are synthesized by stimulating coalescence-mediated necking, which enables the formation of strong crystallographically coherent necks between adjacent grains. The work places a general emphasis on manipulating crystal growth on the nanoscale and on preparing highly porous polycrystalline bulk ceramics with improved mechanical rigidity.
