Highly porous metals and ceramics [PDF]

open access: yesMaterials Science and Technology, 2010
Cellular solids are a class of highly porous materials that covers a wide range of structures, such as foamed materials, replicated porous or additive manufactured structures, honeycombs, lattice structures, interconnected fibres or hollow spheres and syntactic foams. The pores can be more or less closed or completely open.

Mechanical strength of highly porous ceramics [PDF]

open access: yesPhysical Review B, 1991
This paper reports on the mechanical strength of highly porous ceramics in terms of the Weibull and Duxbury-Leath distributions. More than 1000 side-crushing strength tests on silica-catalyst carriers of various particle sizes have been performed in series. Within a series, preparation conditions were kept constant.

Porous Piezoelectric Ceramics

open access: yes, 2010
Porous piezoceramics find nowadays many applications as ultrasonic transducers. The introduction of a controlled porosity into a piezoelectric ceramic could in fact strongly improve the acoustic performances for this kind of applications. In this chapter the more recent literature on the processing of porous ceramics has been reviewed.
