A meta-analysis of the mechanical properties of ice-templated ceramics and metals [PDF]
, 2015 Ice templating, also known as freeze casting, is a popular shaping route for macroporous materials. Over the past 15 years, it has been widely applied to various classes of materials, and in particular ceramics.

Influences of composition of starting powders and sintering temperature on the pore size distribution of porous corundum-mullite ceramics [PDF]
, 2005 Porous corundum-mullite ceramics were prepared by an in-situ decomposition pore-forming technique. Starting powders were mixtures of milled Al(OH)3 and microsilica and were formed into oblong samples with a length of 100mm and a square cross-section with

Gelcasting of carbide ceramics
Journal of the Ceramic Society of Japan, 2008 In this article, the aqueous gelcasting of carbide ceramics (SiC, TiC, B 4 C) was studied systematically. For SiC with the addition of Al 2 O 3 and Y 2 O 3 as sintering additives, tetramethylammonium hydroxide (TMAH) is used as the dispersant for making slurry with high solids lading and low viscosity.

A PCE-based rheology modifier allows machining of solid cast green bodies of alumina [PDF]
, 2015 The performance of a poly(carboxylate ether) (PCE)-based superplasticizer to enable the machining of green bodies that are solid cast from suspensions of alumina was investigated. An alumina loading of 35 vol% in the presence of 1.25 wt% superplasticizer

Catalytic chemical vapor deposition synthesis of single- and double-walled carbon nanotubes from α-(Al1−xFex)2O3 powders and self-supported foams [PDF]
, 2009 An investigation of the potential interest of α-alumina–hematite foams, as opposed to powders, as starting materials for the synthesis of carbon nanotubes (CNTs) by catalytic chemical vapor deposition method was performed.
