noun[mass noun] Chemistry
The property of becoming less viscous when subjected to an applied stress, shown for example by some gels which become temporarily fluid when shaken or stirred.
- A very desirable property in many applications is thixotropy, in which the material behaves as a gel or very viscous liquid at rest or subject to mild shear, but flows freely when subjected to a larger shear.
- When cold it is difficult or impossible to ‘shake out’ the stiffening due to enhanced thixotropy.
- Another property of muscles that increases resistance is thixotropy.
- Example sentences
- These systems are called thixotropic and are characterized by a difference in viscosity, depending on the speed at which the shear force is applied.
- Its use in stabilizer systems is advantageous because it exhibits thixotropic rheological properties, requiring little change in processing conditions while providing stability to the finished product.
- Another advantage of the theory is that it provides a possible explanation for an important quantitative difference between the thixotropic properties of relaxed and contracting fibers, the rate of stiffness recovery.
1920s: from Greek thixis 'touching' + tropē 'turning'.
