The invention belongs to the technical field of ITO target material production, particularly relates to a size control device and method for avoiding waste of ITO target materials, and aims at solving the problems that in the prior art, a blank is heated unevenly, so that the transverse sintering shrinkage rate difference is large, the target material utilization rate is low, and the lower portion of the blank and other portions of the blank are heated differently. In order to solve the problem that the shrinkage resistance of a green body shows that the shrinkage rate is reduced in a gradient mode from top to bottom, according to the scheme, the device comprises a sintering furnace and a sintering bearing table located in the sintering furnace, a door plate is slidably connected into the sintering furnace, and an arc-shaped limiting plate is fixedly connected to the inner wall of the side, away from the door plate, of the sintering furnace; according to the sintering furnace, by driving ...
