Ceramics - Viscosity Measurement of Ceramic Slurries with the RheolabQC

The Anton Paar RheolabQC makes rheological checks routine and easy. Measurements of slurries in the ceramic industry describe important transport and processing behaviors.

Rheological measurements in the ceramic industry

The processing and transport characteristics of slurries are heavily dependent on their rheological properties. Knowledge of the rheological parameters is therefore essential, particularly when transporting a large amount of slurry. Flow curves are used to represent the pipe flow, the flow resistance and pressure difference. Besides measuring flow and viscosity curves, the yield point can also be calculated, e.g. using the Herschel-Bulkley model. Measuring the yield point and the viscosity function gives an important information for a better understanding how slurries flow in pipes. It also helps to solve problems with slurries which are difficult to pump.

The rheometer system RheolabQC with the sandblasted cylinder measuring system CC27 according to ISO 3219 is perfectly suited for the control of the pumping process and for the characterization of slurries.

The Anton Paar Rotational Rheometer RheolabQC

The RheolabQC is a unique rotational rheometer that combines latest technologies with easy handling. It features a high precision encoder and a highly dynamic EC motor.

  • You can choose between operating the rheometer stand-alone or software-controlled with RheoCompass™, a modern and highly intuitive rheometer software.
  • Preprogrammed standard templates allow to determine viscosity and yield point by the push of a button.
  • The RheolabQC can be operated with a huge variety of accessories. The automatic component recognition Toolmaster™ ensures error-free selection of the measuring geometries.
  • Measurements with the concentric cylinder measuring systems accord to ISO 3219 and DIN 53019
  • For applications in the ceramic industry we recommend the sandblasted concentric cylinder measuring system set CC27 or CC39, the sandblasted surface reduces wall slipping effects.
  • Optional temperature control systems are available, for example the Peltier temperature control C-PTD180/AIR/QC (0 °C to +180 °C).

Good to know

Viscosity measurement at different shear rates is essential for optimizing the flow properties of slurries. A measurement with the RheolabQC is outlined here with information on the yield point.



The yield point tells us at which shear stress the slurry starts to flow. For this slurry it is 12 Pa, calculated with the Herschel-Bulkley method.
