Definition
Meaning and Definition
The property of a fluid or gel to become less viscous when agitated and return to a more viscous state when left undisturbed.
In rheology, thixotropy refers to the time-dependent shear thinning behavior of certain non-Newtonian fluids, where viscosity decreases under shear stress and recovers over time when the stress is removed, observed in materials like paints, ketchup, and clays.

Examples of “thixotropy” in a Sentence
adjective
British English
- The paint has a thixotropic consistency that prevents dripping.
American English
- This gel is thixotropic, so it flows easily when shaken.
Usage
Meaning in Context
Business
In manufacturing, thixotropy is critical for products like paints and adhesives that require easy application and firm setting.
Academic
In physics and chemistry, thixotropy is studied within rheology to analyze complex fluid dynamics and material properties.
Everyday
Rarely used in casual conversation; occasionally mentioned when explaining why ketchup flows after shaking.
Technical
Essential in rheology, material science, and engineering for characterizing and controlling fluid behavior in industrial processes.

Common Mistakes When Using “thixotropy”
- Mispronouncing as /θɪkˈsoʊtrəpi/ or confusing with 'thixotropic' (adjective).
- Using it to describe any viscosity change without time-dependent recovery.
FAQ
Frequently Asked Questions
Thixotropy is the property of certain fluids or gels to become less viscous when subjected to shear stress and return to a higher viscosity when the stress is removed.
It is commonly observed in everyday substances like ketchup, toothpaste, and paints, as well as in industrial materials such as drilling muds and adhesives.
Shear thinning refers to an instantaneous decrease in viscosity with shear rate, while thixotropy includes a time-dependent recovery of viscosity after shear cessation.
Thixotropy is vital for products that need to be easy to apply or pump but then set firmly, enhancing performance in coatings, food processing, and construction materials.
The property of a fluid or gel to become less viscous when agitated and return to a more viscous state when left undisturbed.
Thixotropy is usually technical in register.
Thixotropy: in British English it is pronounced /θɪkˈsɒtrəpi/, and in American English it is pronounced /θɪkˈsɑːtrəpi/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of 'thick' syrup turning 'thin' when stirred: thixotropy makes thick substances thin under agitation.
Conceptual Metaphor
A stubborn crowd that disperses when pushed but regathers when left alone.
