Air in Ceramic Slurry
Air in Ceramic Slurry
(OP)
Can anyone tell me if there is a method for removing air from ceramic slurries ?.
We are dipping plastic patterns in the slurry but bubbles are causing scrap on the finished castings.
Anti - Foams are not very effective.Dipping at an angle is better but again not totally effective.
Speed is an important factor.

Ceramicguy but unfortunately not an option....a full scale production process whereby a board containing the moulds is dipped into the pot and rotated every two minutes.Vacuuming would be too expensive and take too long.
Thanks anyway mate
