The ceramic sintering setter plate provided by the utility model comprises glue discharge holes 100, wherein the glue discharge holes 100 are arranged on the ceramic sintering setter plate in a multi-row array form, and the diameter of each glue discharge hole 100 is defined as D0The distance between the centers of the adjacent glue discharge holes 100 in a row is defined as S1，D0Satisfies the following conditions:
2mm≤D0≤8mm。
according to the ceramic sintering setter plate provided by the utility model, the glue discharging holes 100 can increase the contact area between the lower-layer green body and the air flow during ceramic sintering, and increase the glue discharging path, so that organic matters in the green body can be effectively discharged, the problems of surface carbon residue, color difference, poor performance and the like of the lower-layer ceramic substrate are avoided, and the layout rationality of the glue discharging holes 100 can be improved and the quality of a ceramic sintered finished product is improved by limiting the size range of the glue discharging holes 100 and the distance between adjacent glue discharging holes in one row.
Specifically, if D0And S1If the ratio of (a) is too small, the glue discharging holes 100 are distributed too sparsely, the communication effect between the upper layer and the lower layer of the setter plate for ceramic sintering is poor, and the glue discharging effect is poor, so that the ratio is not less than 0.1. If the ratio is too large, the strength of the setter plate for ceramic sintering is lowered, the load-bearing capacity of the setter plate for ceramic sintering is impaired, and the number of stacked layers of green compacts is limited.
The material of the setter plate for ceramic sintering provided by the utility model comprises a molybdenum material. The sintering bearing plate for ceramic sintering, which takes molybdenum as a main component, has excellent temperature resistance and strength, and can ensure the stable ceramic sintering.
The center distances of the glue discharging holes 100 in different rows may be the same or different, and in some embodiments, the center distances of the adjacent glue discharging holes 100 in each row are the same. The glue discharging holes 100 in two adjacent rows may be staggered. The staggered arrangement can ensure that the air flow is more uniformly contacted with the green body at the lower layer during the ceramic sintering, and further improves the glue discharging effect.

it can be understood that the thickness of the sintering setter plate for ceramic sintering is increased to result in the height of the glue discharging holes 100 being too large, and the gas flow passing through the glue discharging holes 100 is likely to generate circulating vortex or turbulent flow, which results in the difference of the gas flow in different glue discharging holes 100 being increased, thereby affecting the uniformity of glue discharging of the green body of the lower layer and causing the performance of the sintered ceramic substrate of the lower layer to be reduced. The reduction in thickness of the setter plate for ceramic sintering results in a reduction in strength of the setter plate for ceramic sintering and a reduction in load carrying capacity. The state of the air flow in the glue discharging hole 100 is related to the ratio of the height to the diameter of the glue discharging hole, and according to the result of calculation and analysis, the thickness of the sintering bearing plate for ceramic sintering is limited, the relation between the thickness and the diameter of the glue discharging hole 100 is controlled, the number of laminated layers of green bodies on the sintering bearing plate can be increased on the premise of ensuring the performance of the ceramic substrate on the lower layer, and therefore the production efficiency is further improved.
