ISO 20379:2018 - Thixotropic Behaviour Measurement of Ceramic Slurry

Fine ceramics (advanced ceramics, advanced technical ceramics) — Measurement of thixotropic behaviour of ceramic slurry by use of a rotational viscometer

Slurry processing is central to several advanced ceramics manufacturing routes, such as tape casting, slip casting, and screen printing. These slurries often exhibit thixotropic behaviour, where their viscosity decreases under shear and recovers over time. ISO 20379:2018 provides a clear methodology for measuring such behaviour using rotational viscometers.

Details and methods:

• Focuses on high-solid ceramic slurries exhibiting non-Newtonian (thixotropic) properties
• Specifies use of coaxial double cylinder, cone and plate, or parallel plate rotational viscometers
• Outlines two main evaluation methods:
  • Hysteresis measurement of the flow curve
  • Time-dependency of shear stress at constant low shear rate

Key requirements:

• Careful preparation and degassing of slurry samples
• Calibrated test equipment and precise temperature control
• Detailed test protocols for measuring and analyzing thixotropy
• Comprehensive reporting of procedures and measurement results

Target users:

• Ceramic manufacturers using slurry-based processes (tape casting, slip casting, etc.)
• R&D labs developing new formulations for advanced ceramics
• Quality control and materials testing facilities in ceramics industry

Business/practical impacts: Standardized measurement of thixotropy leads to more consistent processing and quality in products such as multilayer capacitors, fuel cells, and robust coatings. It supports development of stable, easy-to-handle slurries that improve manufacturing throughput and reduce rework.
