In powder injection moulding (PIM) the powder characteristics in particular the particle size affect strongly the feedstock properties and hence further processing. In this study nanostructured zirconia powder with primary particles of 20nm was blend in different fractions with a coarse-grained, micron sized zirconia powder to investigate the influence of specific powder surface on achievable solid loadings, processability and debinding properties such as on the sintering behaviour.
