Processing Nanostructured Structural Ceramics
Abstract
The processing of ceramic nanopowders into components has been investigated via a series of research projects, each focusing on a different stage of the manufacturing route. As a result of the work performed, progress has been made into the ability to control the agglomerates present in the powder resulting in the production of a free-flowing and crushable powder for die pressing; the formation of low viscosity but high solids content suspensions that enable wet green forming routes to be used that yield homogeneous and high quality green bodies and finally, the ability to achieve fully dense ceramics with average grain sizes of just 65 nm by pressureless sintering. All the work presented here is based on yttria-partially stabilised zirconia ceramics; an additional observation for this material is that the level of dopant required appears to be significantly reduced compared to conventional submicron grain sized ceramics.
