✦ Synopsis

The capillary rheometer has been used to determine the rheological properties of various carbon mixes consisting of petroleum coke as filler and coal tar pitch as binder. It has been shown that the carbon mixes containing various proportions of binder behave rheologically as Bingham material with yield stress and plastic viscosity. When binder level exceeds a certain optimum level, plastic viscosity shows a steep fall from 20 x 105 to 2 x 10' P (poises), while yield stress does not show much variation. A comparatively better rheological behaviour is observed with capillary rheometer than that with parallel plate viscometer.
