Abstract:
A process for making an extruded dried ceramic product, which process includes the steps of:extruding an elongated moist profile in a downward direction, the profile comprising a moist ceramic composition or a moist precursor thereof;drying the extruded profile, at a position below the extrusion, by subjecting it to microwave radiation having a frequency of 0.3.times.10.sup.9 -1.times.10.sup.10 Hz to cause the profile to become progressively drier in the downward direction in which it is extruded;continuously supporting the extruded profile during the extrusion and drying at a position where it has been at least partially dried by the microwave radiation; andintermittently and successively separating lowermost portions of the dried profile from the remainder of thereof at a position below said support position, to provide dried lengths of the profile.
