Abstract
The invention relates to a method of producing a ceramic article. According to the invention, a slip is pressure cast in a mould (12) in order to form a deposit (20) and a solution (10) containing a deflocculating agent is filtered onto said deposit (20).
Claims13
A method of producing a ceramic article (30), characterized in that it comprises the steps consisting in:
- casting a slip (8) under pressure into a mold (12) in order to form a deposit (20);
- and
- filtering a solution (10) containing a deflocculant through the deposit (20).
A device for producing a ceramic article (30), comprising a mold (12) and a first tank (4) suitable for containing a slip (8), characterized in that it comprises a second tank (6) suitable for containing a solution (10) and means (14) for injecting under pressure, into the mold (12), alternately the slip from the first tank and the solution from the second tank.
