Method for eliminating ITO green body edge microcrack defects in pressure slip casting process
Disclosed is a method for eliminating ITO green body edge microcrack defects in the pressure slip casting process. The method comprises the steps that a glass plate is arranged on an inward concave face of a left inner mold and a contact face of a right inner mold, the glass plate is pasted on the inward concave face of the left inner mold at this moment, left long rectangular-ambulatory-plane cavities are formed at the non-pasted positions in the height direction and the length direction at equal intervals, the glass plate is pasted on the contact face of the right inner mold, right long rectangular-ambulatory-plane cavities are formed at the non-pasted positions in the height direction and the length direction at equal intervals, spraying materials are sprayed to the left long rectangular-ambulatory-plane cavities and the right long rectangular-ambulatory-plane cavities respectively to form a left long rectangular-ambulatory-plane spraying band and a right long rectangular-ambulatory-plane spraying band, and a water stopping area is formed by the left long rectangular-ambulatory-plane band and right long rectangular-ambulatory-plane band in mold closing in the forming process; the density gradient and a transition layer of an ITO green body in the forming process are eliminated through the water stopping area, it is guaranteed that the overall density and planeness of the ITO green body are consistent, and then the microcrack defects happening to the edge of the ITO green body are eliminated.
