Abstract
A method of forming a ceramic product, the method comprising producing a ceramic forming mixture in the form of a slurry, causing the slurry to form, extruding the formed slurry to produce a plurality of lengths of extruding material each with a diameter of less than 10 mm, firing the extruded material so as to partially sinter the extruded material, forming the partially sintered extruded material into a required shape for a product, and subsequently firing the shaped partially sintered extruded material to form the ceramic product.
Claims20
A method of forming a single ceramic product, the method comprising:
- producing a ceramic forming mixture in the form of a slurry;
- causing the slurry to form, extruding the formed slurry to produce a plurality of lengths of extruded material each with a diameter of less than 10 mm;
- firing a layer formed of the plurality of lengths of the extruded material so as to partially sinter the plurality of lengths of extruded material, with increased sintering at the top of the layer and less sintering at the bottom of the layer;
- pressing multiple lengths of the partially sintered extruded material into a shape comprising the pressed multiple lengths of the partially sintered extruded material, wherein the shape is a required shape for the single ceramic product;
- wherein the less sintered lengths of extruded material break down during the pressing process and act as a pressing aid to hold the more sintered lengths of extruded material together in the pressed shape;
- and
- subsequently firing the shape to form the single ceramic product.
