Název v původním jazyce

Processing, microstructure, properties, applications and curvature-based classification schemes of porous ceramics

Popis výsledku v původním jazyce

Porous materials are heterogeneous media with unique microstructures, leading to interesting effective properties on which many different applications are based. In particular, porous ceramics combine the generic performance features resulting from the geometry and topology of the porous microstructures with the intrinsic properties of ceramics as a specific class of materials. Obviously the applications of porous ceramics are based on their structural and functional properties and performance, which are due to their microstructure, the latter being a result of the raw materials used and their processing. As a consequence of the ubiquity and diversity of porous ceramics it is not easy, especially for beginning materials scientists and engineers, to get a general overview on porous ceramics, in particular because of the many different categories used for their classification. A key feature of the microstructure of porous ceramics that is often neglected so far is the pore space surface curvature. Resulting from processing and crucial for determining the properties and thus the potential applications, it is one of the most important microstructural characteristics of porous materials. Moreover, quantitative measures based on the pore space surface curvature can be conveniently quantified by stereology-based microscopic image analysis or tomography. Therefore, the pore space curvature is one of the most important criteria for a rational classification of porous ceramics. Based on this fact we propose and explain a new classification scheme into five basic types of porous microstructures, in which the curvature is the key criterion for the classification and a practical guide for property estimation, e.g. the choice of an adequate property-porosity relation for prediction. This new, microstructure-based, classification is embedded in a discussion of the more traditional classification schemes for porous ceramics based on processing, properties and applications.
