Problems solved by technology

Since the target material is in a soft state during high-temperature sintering, if the weight of the target material is large with these two methods, pads or balls are easy to embed into the target material at high temperature, resulting in poor sliding effect, and it is difficult to effectively prevent friction caused by frictional resistance. irregular deformation of

Embodiment Construction

[0010] The invention will be described in further detail below in conjunction with specific embodiments.

[0011] The bearing surface of the setter plate is provided with a positioning concave hole, which is a through hole. use as figure 1 with figure 2 In the shown powder distributor 1 , the center of the powder distributor 1 protrudes downwards with a tubular central positioning part 14 , and its lower end protrudes downwards. Put powder distributor 1 on the setter. The center positioning portion 14 of the powder distributor 1 is inserted into the positioning concave hole of the setter, whereby the powder distributor 1 is fixed on the setter.

[0012] The powder distributor 1 includes a distribution orifice plate 12 and a vertical peripheral riser 11, both of the distribution hole plate 12 and the peripheral riser 11 are closed circular rings, and the end of the distribution hole plate 12 is connected to the waist of the peripheral riser 11 away from the center , the ho...

Abstract

The invention relates to a powder distributor for placing a target material green body, a positioning piece and a sintering method of a rotary target material. A powder pile with a slope at the top is piled on a load bearing plate by using auxiliary sliding powder, and then the rotary target material green body is placed on the slope of the powder pile. During sintering, the target green body shrinks to drive alumina powder pile to move inwards in the radial direction relative to the load bearing plate, so that the horizontal static friction force between the rotating target green body and the load bearing plate is converted into sliding friction force, and sliding effect after the auxiliary sliding powder forms the powder pile is superior to the sliding effect of paving one layer in the prior art; the friction resistance between the target material and the load bearing plate can be better reduced, friction resistance generated when the target material green body shrinks is reduced, and irregular deformation and cracking of the target material caused by the friction resistance are prevented.

Description

technical field [0001] The invention relates to the technical field of ceramic target sintering, in particular to a powder distributor for arranging target green bodies, a positioning piece and a sintering method for a rotating target. Background technique [0002] In the traditional process of rotating target sintering, the green body is directly placed vertically on a sintering plate such as alumina, and then put together into a sintering furnace for sintering. During sintering, the target green body will shrink inward as a whole. The position where the bottom of the target is in contact with the setter will generate greater frictional resistance. This frictional resistance will prevent the bottom of the target from shrinking inward, so that the amount of deformation generated by the shrinkage of the bottom of the target is different from the amount of deformation generated by the upper part. As a result, the bottom of the target is deformed or even cracked outwardly, and ...
