This paper reviews the use of ceramic foams as structured catalyst supports. They are open-
cell ceramic structures that may be fabricated in a variety of shapes from a wide range of …

Open‐cell hydroxyapatite (HA) foams, produced through the novel technique of gelcasting
foams with relative porosities ranging from 0.72 to 0.90, were characterized for pore‐size …

Ceramic foams constitute a new structural material characterized by a high porosity and high
superficial area, formed by megapores interconnected by filaments. This results in a …

The permeability of crystal-poor obsidian flow and pumice samples from Medicine Lake
Volcano, USA, are measured to assess (1) the existence of a critical vesicularity (porosity) …

An improved technique has been developed for the successful fabrication of reticulate
porous ceramics (RPCs) with strong struts, using polyurethane sponge as the template. In …

Cellular ceramics are a class of high-porosity materials that are used or are being
considered for a wide range of technological applications. A critical aspect of this …

Ceramic foams with a gradient porosity were manufactured using a self foaming process of a
Si/SiC filled silicone resin in the temperature range of 220–270° C. Subsequent pyrolysis at …

Commercial polyurethane sponges with cell size of≈ 11 pores per inch were chosen to
produce SiC-based reticulated porous ceramic (RPC) by the replication process. The …

Alkali-bonded ceramics and foams with tailored porosity have very interesting applications
as thermal insulators, catalysts, filters, etc. Alkali-bonded ceramics were prepared starting …

Silicon carbide (SiC) with ultra high porosity and unidirectionally oriented micrometer-sized
cylindrical pores was prepared using a novel gelation–freezing (GF) method. Gelatin, water …
