MOLDING APPARATUS FOR PRESSURE CASTING OF CERAMIC NANOPOWDER AND MANUFACTURING METHOD OF CERAMIC BLOCK USING THE MOLDING APPARATUS

摘要

The present invention relates to a molding apparatus for pressure slip casting of ceramic nanopowder slurry and a manufacturing method of a ceramic block using the same. The molding apparatus includes a storage tank for storing slurry containing ceramic nanopowder; a mold for molding the slurry in a predetermined block shape by receiving the slurry through a first pipe connected to the storage tank; and a compressed gas supplying device for supplying compressed gas by being connected to the storage tank through a second pipe. The compressed gas supplied from the compressed gas supplying device is supplied to the upper part of the storage tank through the second pipe, and the slurry stored in the storage tank is introduced into the mold through the first pipe connected to the storage tank by the pressure of the compressed gas. The slurry introduced into the mold receives downward pressure by the pressure of the compressed gas, and water contained in the slurry is discharged to the outside by passing through a filter installed in the mold. The ceramic nanopowder contained in the slurry is formed in the ceramic block shape by being filtered in the filter. According to the present invention, the molding apparatus can be used for a long time with a low damage possibility even if the molding apparatus is repeatedly used. Moreover, the molding apparatus can mold the ceramic nanopowder with a target thickness (for example, 1.5 cm or more) and can obtain a solid object.
