Title

Alumina Slurries Inclusion in Freeze Casting

Authors

Abstract

Using aqueous slurries to mould alumina parts, freeze-drying techniques were used to press less slip moulding. Glycerol has been used to eliminate defects associated with expansion and ceramic surface rejection during the freezing of water as a water solidification agent. Castable alumina slurries with solids up to 60 per cent loading were prepared and characterised using viscosity and zeta-potential measurements with and without glycerol additions. In order to achieve highly dense alumina bodies with a uniform microstructure, frozen sections were dried under vacuum by ice sublimation to obtain a net shape of green bodies. The combined effects of high solids loading slurries, less than 56.4 % volume and glycerol additions were essential for freeze casting. The feasibility of complex formation was demonstrated by using Freezing principles and aqueous alumina slurries with high mixing of solids. This led to freeze formed samples were processed with a uniform microstructure in the absence of ice formation related defects.

Key Words

freeze casting, alumina slurries, glycerol, ceramic, microstructure, surface rejection.
