Document Type and Number:
Japanese Patent JP6872395
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an extrusion molding method capable of forming ceramic formed product which contains high aspect ratio particles and in which longitudinal direction of the particles are designed in approximately parallel with thickness direction of a formed part having a wall shape or plate shape.SOLUTION: There is provided an extrusion molding method for a ceramic formed product, in which, with an extrusion molding mouth metal 4 on which a slit 8 is arranged for extrusion molding of the ceramic formed product from a forming ingredient, in which the slit 8 comprises a front slit step part 8a located at upstream side in extrusion direction in the extrusion molding and a rear slit step part 8b located at downstream side in extrusion direction, and the width of the rear slit step part 8b is 3 to 27 times of the width of the front slit step part 8a, the ceramic formed product comprising a formed part having a wall shape or a plate shape is formed by extruding the ingredient 11 containing first particles 10 as particles having 2 or more and less than 300 of aspect ratio in a manner it passes through the front slit step part 8 of the extrusion molding mouth metal 4 and then passes through the rear slit step part 8b.SELECTED DRAWING: Figure 3C
