Method for the production of large-size densely sintered ceramic plates with a low wall thickness

摘要

The specification describes a method for the production of densely sintered large ceramic plates of small thickness. The ceramic composition is first extruded by means of an extruder and is then rolled out from the resulting billets in a direction perpendicular to the extrusion axis, this rolling operation is carried out by a further rolling out operation in the axial direction of the billets. The cutting out of the plates to the desired format is by means of a pressing knife acting perpendicularly with respect to the plate plane. Following this the plates are dried and fired.
