Abstract

The invention discloses a single-surface pressure grouting forming method of an ITO rotating target blank body and a mold. The mold is arranged on a rotating platform, and is provided with a cylindrical molding cavity inside for accommodating pulp; micro holes are formed in the mold wall on the inner side and the outer side of the cylindrical molding cavity; the pulp is injected in the cylindrical molding cavity of the mold; and when the mold rotates to form a centrifugating effect, compressed air is fed in the cylindrical molding cavity through the micro holes in the mold wall on the inner side of the cylindrical molding cavity for single-surface pressurization to the pulp from inside to outside, so that water in the pulp is discharged by the micro holes in the mold wall on the outer side of the cylindrical molding cavity to form the ITO rotating target blank body. The centrifugal grouting formation is adopted to combine with the single-surface ventilation pressurization and single-surface drainage modes; the pulp has no need to feed in the forming process; and the formed blank body is uniform in structure, cannot generate the interlayer defect, and further improves the density. The inner side of the formed cylindrical blank body cannot be bonded with the mold, so that the demolding yield rate is higher, and the process is simpler and more convenient.

Description

technical field

[0001] The invention relates to a method for forming a rotary ceramic target body and a mold used therefor, in particular to a single-side centrifugal pressure grouting molding method and mold for an ITO rotary target body. Background technique

[0002] ITO is the abbreviated name of Tin-doped Indium Oxide. The meaning of ITO refers to a kind of indium tin oxide material. The ITO rotary target body refers to the cylindrical blank made of indium tin oxide before sintering. The inner diameter is generally 150~200mm, the outer diameter is 165~220mm, and the cylinder height is 300~350mm.

[0003] At present, the molding methods of the ITO rotating target blank usually include rubber sheath dry powder cold isostatic pressing and grouting molding using ordinary gypsum as the mold. Chinese patents (CN 103193262 A, CN 103787651 A) and others have reported methods for preparing high-density ITO targets by cold isostatic pressing. After cold isostatic pressing, the de...
