    Rheological analysis of powder injection moulding of feedstock based on aluminium oxide powder and multicomponent partly water-soluble polymeric binder is carried out with the aim to produce the defectfree and non-porous parts. As this process is characterized by the flow of highly filled (60 vol.%) compound into a mould cavity, rheological properties supplemented by thermal and pressure-volume-temperature characteristics are measured and described. Structural changes of the feedstock caused by shear deformation are quantified in terms of yield stresses obtained using the Herschel-Bulkley and Casson models. For a description of non-monotonous flow behaviour of the feedstock, the rheological model valid in the whole shear rate range measured is developed.
