Description
Technical Field
The invention relates to the technical field of target processing production, in particular to an isostatic pressing method for a large-size planar ITO target.
Background
The rapid development of the flat panel display industry places higher demands on the materials used. Larger size, higher density, lower resistivity, and higher utilization are required for ITO targets. One of the major difficulties in the preparation process of the ITO target is large size, and the difficulties mainly include oil pressure forming, isostatic pressing forming, process shipping and the like. When the blank is subjected to isostatic pressing, the large-size blank has low strength, the target material is thin, the target material needs to be turned manually in a general normal shipping or packaging process, and the blank is very easy to crack or be damaged in the turning process. The cracking of the green body can directly cause the target material to be scrapped, so that a large amount of production cost loss is caused, and the yield is influenced or the order cannot be completed directly. It becomes important to solve this problem.
