The knowledge of flow behaviour of ceramic suspensions is important condition for control of ceramic wet processing. The flow behaviour can be stated by the rheological measurements. The paper deals with measurement of the concentrated ceramic suspensions rheological behaviour The procedure of rotational rheometry experimental data evaluation from rotational viscometer with coaxial clylinders is presented. The correction of data obtained by direct measurement with non-Newtonian suspension is proposed with the aim to obtain the relevant flow curve, i.e. dependence of shear stress on shear rate.
