Ice is cracking ceramics in a vessel

Ice is cracking ceramics in a vessel

Ice is cracking ceramics in a vessel

I have a vessel filled with water and two ceramic plates.  One on top and one on the bottom.  The top and bottom must be rigid and the distance between them can not change.  The fluid must remain between the ceramic plates and the fluid must be distilled water.  Dose any one have a suggestion on how to prevent the ice formation from cracking the ceramics.  Thank you.

RE: Ice is cracking ceramics in a vessel

WOW- -- Ice formation is perhaps one of the most cumulatively destructive processes around. I'm not sure you can really stop it effectively. You might try using a flexible walled vessel so that the expansion due ot the phase change is absorbed there. Although I dont really think that will bee very effective. You also might be able to sping load one of the ceramics so that it can be pushed by the ice .

good luck

RE: Ice is cracking ceramics in a vessel

So, don't let ice formation start?

Wasn't it designed for this purpose to begin with?

Why not use a material that doesn't crack?


RE: Ice is cracking ceramics in a vessel

Does the container need to be completely full of water (no air space at all?

How about adding a hollow balloon inside that can be squeezed to take up the expansion and contraction?

RE: Ice is cracking ceramics in a vessel

Is the water stirred?  Motion will slow the ice formation.  you can pump slush that is below the bulk freezing point, just don't let it stop moving.
I really think that you need to address the prevention of ice formation in the first place.

What is the system?

Corrosion never sleeps, but it can be managed.

RE: Ice is cracking ceramics in a vessel

Are the ceramics porous?  If so, then the situation is hopeless, since the water freezing inside pores in the ceramic will crack it (this is what turns mountains into beaches).
