Access from EThOS:
Industrial exploitation of ceramic nanopowders is inhibited by their poor flowability and strong tendency to agglomerate. To achieve good flowability and die filling characteristics, controlled agglomeration is required whilst the strength of the agglomerates is minimised so that they crush into primary particles when die pressed. Yttria stabilised zirconia nanopowders with a primary particle size of ~16 nm were obtained through different drying routes from an aqueous suspension and characterised in terms of flowability and agglomerate strength.
