METHOD FOR MAKING CERAMIC THIN EXTERIOR PART

摘要

A method for making a thin ceramic part involves making a casting slurry including a ceramic powder, a solvent, a binder, a plasticizer, and a dispersant. The casting slurry is tape casted to achieve a single layer green tape. At least two single layer green tapes are laminated to form a green tape lamination. The green tape lamination is dry pressed, dried, shaped, degreased, and fired to achieve the exterior component required.

1. A method for making a ceramic thin exterior part, the method comprising:
preparing a casting slurry comprising a ceramic powder, a solvent, a binder, a plasticizer, and a dispersant; tape casting the casting slurry to achieve a single layer green tape; laminating at least two single layer green tapes, to form a green tape lamination, comprising:
coating a layer of casting slurry on a surface of one single layer green tape; andsandwiching the layer of casting slurry between two single layer green tapes to form the green tape lamination; dry pressing the green tape lamination to form a dry pressed green tape lamination; drying the dry pressed green tape lamination to remove the solvent in the green tape lamination and form a dried green tape lamination; shaping the dried green tape lamination into a shaped green tape lamination; degreasing the shaped green tape lamination by heating to achieve a degreased green tape lamination; and firing the degreased green tape lamination.
