In most cases, I have seen that the storage and loss modulus of polymeric gels decrease with temperature.
Here, I have worked with ceramic slurry and I have found that the storage and loss modulus is increasing with temperature. Can anyone help me with this
Mr. Deng published a nice article based on preparation and characterization of porous mullite ceramics via foam-gel casting. I attached that file which might be useful for you
Generally, the storage and loss modulus are increased when gelling is increased and vise versa.
To get a specific answer, the details of the slurry system must be given.
Imad DisherThank you for your response.
It is a ceramic slurry with a foaming agent added. I have found that the storage and loss modulus increased with increase in temperature.
What does the cross over point indicate in temperature sweep and how can I correlate it with porosity?
@ Soumya Devavarapu:
- Is the any polymeric additives and/or gelling reagents in your slurry?
- Any hydrolyses process?
