Case corrugated zirconium dioxide electric ceramic burning plate and manufacturing method thereof

Abstract

The invention discloses a case corrugated zirconium dioxide electric ceramic burning plate and a manufacturing method thereof, belongs to ceramic molded products using the zirconium dioxide as base materials, in particular to a bracket and a screen board for charging a sintering furnace special for ultra-thin zirconium dioxide electric ceramic products. The case corrugated zirconium dioxide electric ceramic burning plate comprises the following raw material components in mol percentage: 87 to 96 mol percent of zirconium dioxide ZrO2 and 4 to 13 mol percent of yttrium oxide Y2O3; and the manufacturing method for the case corrugated zirconium dioxide electric ceramic burning plate comprises the following steps: (1) preparing yttrium oxide stabilized zirconium dioxide ceramic materials; (2) performing dry pressing molding; and (3) sintering. The invention provides the case corrugated zirconium dioxide electric ceramic burning plate in which a plurality of V-shaped strips are connected and compounded with a saggar into a whole, and the manufacturing method thereof. The process for putting the V-shaped strips is saved; the work force is reduced; and the labor intensity of workers is lowered. The sintering space is enlarged without the matching of the saggar; the production capacity of the sintering furnace is improved, and the sintered product rate is improved. The electrical performance and physical performance of the products are greatly improved.

Description

technical field [0001] The invention relates to a corrugated box body type zirconia electronic ceramic setter and a manufacturing method thereof. It belongs to ceramic molded products with zirconia as the base material, in particular to brackets and screen plates used for charging in sintering kilns specially used for ultra-thin zirconia electronic ceramic products. Background technique [0002] The sintered carrier of zirconia electronic ceramics utilizes the chemical stability and phase change toughening mechanism of zirconia materials. It has high temperature resistance, high strength, high load softening point, strong thermal shock resistance and no bonding with characteristics of chemical reactions. It is widely used in the field of electronic ceramic production. [0003] The electronic industry has continuously improved the performance requirements of ceramic electronic components. When sintering disc-shaped electronic components, manufacturers of ceramic electronic ...

AI Technical Summary

Problems solved by technology

A lot of labor is required, and the labor intensity of the workers is high

[0006] ② It needs to be used together with the sagger. The volume of the sagger is relatively large, which occupies the sintering space and reduces the production capacity of the sintering furnace

[0007] ③During the sintering process of the product, the green body of the product is easy to loosen and unstable, which easily leads to deformation of the sintered product, and the yield of the finished product is not high

[0008] ④ More importantly, there are gaps between the V-shaped strips, which are not closed. During high-temperature sintering, the corundum mullite atmosphere passes through the gaps and chemically reacts with the product, reducing the electrical and physical properties of the product, and the defective rate of the product is high.
