Nanostructured ceramics: a review of their potential

Abstract

The driving forces for the recent development of nanoscale features in conventional ceramic materials for both mechanical and functional reasons are discussed, and the causes of some of the resulting property enhancements are identified. Examples from the technical literature are examined, and the potential for future applications is assessed in terms of the tradeoff between enhanced properties and the added costs and difficulties of processing ultrafine powders.

Biphasic calcium phosphate nanocomposite porous scaffolds for load-bearing bone tissue engineering

“…The local residual stresses generated by the particulate phase promote crack curving in ceramic matrices, and thus the crack propagates along a wavy path. Apart from imparting high toughness, particulates inclusion in a ceramic matrix also increases the strength of the matrix [45,46]. Further, nanoparticles will also improve sinterability and reduce flaw size [47,48].…”

Electrical, structural, and microstructural characterization of nanometric La0.9Sr0.1Ga0.8Mg0.2O3−δ (LSGM) prepared by high-pressure spark plasma sintering

“…That the electrical properties of solid-state ionic oxides can be modified when these materials are prepared with grain size in the nano-scale has been proposed by several authors in the past few years [1][2][3][4][5][6][7]. Despite the potential impact that such materials can have on the science and technology of these oxides, experimental investigations aimed at forming and characterizing such materials have been limited.…”

“…Additionally, nanoparticle properties are sensitive, not only to the size, but also to the composition and shape [46]. Over several decades, the understanding of quantum size effects has led to many applications in most research fields, like electronics [47], optics [48], catalysis [49], ceramics [50], magnetic data storage [51] and biology [52].…”
