Gelcasting ceramic defense parts [PDF]
The goal of this work was to demonstrate an ability to gelcast and fire a particular defense-related part to net shape and to hold the required tolerances on size and shape with minimal or no post firing machining. The precision required represents a huge increase in the precision currently achievable by standard ceramic processing.

Role of stabilisers in the design of Ti aqueous suspensions for pressure slip casting [PDF]
Colloidal processing has long been used in ceramics to achieve green bodies with high densities, complex shapes and homogeneous microstructures, but they are rarely used to shape metal powders because of their high density and high surface reactivity ...

Gelcast Zirconia-Alumina Composites [PDF]
Near net-shaped parts of zirconia-alumina composites have been successfully formed by gelcasting, a technique which utilizes in situ polymerization of acrylamide monomers. The high solids loading required for gelcasting ({approximately}50 vol %) was obtained by controlling the pH-dependent stability of the aqueous zirconia-alumina suspensions. A strong
