TL;DR: In this article, different methods for the fabrication of monolithic ceramic components possessing multiscale porosity, i.e., with pores ranging from a few nanometers to several hundred microns, are discussed.

TL;DR: The potential of polymer-derived-ceramics can only be fully achieved if the type of fabrication method used is tailored taking into account the specific application of interest as discussed by the authors, and a vast amount of research has been conducted, in the past decade, towards the fabrication and characterization of porous ceramics produced from different polymeric precursors, such as polysiloxane, polycarbosilane and borazine.

TL;DR: In this paper, the authors showed that the presence of the nanowires afforded high specific surface area (SSA) values to the macroporous ceramic foams, ranging from 10 to 110 m2/g.

TL;DR: In this paper, two polysilsesquioxanes, with an empirical formula (RSiO 1.5 ) n R = CH 3 (PMS) and CH 3 6 H 5 (PMPS), were pyrolyzed at 1200°C for 2 ¼h to form SiOC ceramics of variable composition.

TL;DR: In this paper, micro-cellular SiCN and SiOCN foams were produced via two different routes by using a polysilazane preceramic polymer, one route using a mixture of partially cross-linked polysilaxane and poly(methylmetacrylate) microspheres, used as sacrificial fillers, was warm pressed and subsequently pyrolyzed to create microcellular foams.
