Problems solved by technology

[0003] In related technologies, when specifically developing zirconia functional ceramic devices, zirconia is usually first granulated into ultra-fine powder, then pressed into a green body of a certain shape, put into a high-temperature furnace and sintered into porcelain, and finally through sealing, Oxygen sensors are prepared by welding and other processes. In this process, if the zirconia biscuit is directly prepared into components with complex shapes, such as devices with protruding sharp corners or devices with too long length, stress concentration is prone to occur and it is difficult to Forming and other issues, the prepared device is also difficult to meet the technical requirements

Abstract

The embodiment of the invention discloses zirconia ceramic metallized gold-based slurry, a metallized layer and a preparation method, relates to the field of brazing pretreatment materials, has a certain anti-radiation function, and can be used as the metallized layer on the surface of a zirconia ceramic biscuit and brazing of other plastic metals under the condition of anti-radiation dose. The zirconia ceramic metallized gold-based slurry and the metallized layer are prepared from the following components in percentage by mass: 0-20% of inorganic oxide, 15-30% of organic solvent, 5-30% of other organic additives, 5-30% of superfine palladium powder and the balance of superfine gold powder. The zirconia ceramic metallization gold-based slurry provided by the invention is used for realizing zirconia ceramic gold-based metallization.

Description

technical field [0001] The present application relates to the field of brazing pretreatment materials, in particular to a zirconia ceramic metallization gold-based slurry, a metallization layer, and a preparation method. Background technique [0002] Calcia stabilized zirconia ceramics (CSZ), yttria stabilized zirconia ceramics (YSZ), ytterbium oxide stabilized zirconia ceramics (Yb-ZrO 2 ), scandium oxide stabilized zirconia ceramics (Sc-ZrO 2 ) and other functional ceramic devices are widely used in atomic energy, iron and steel metallurgy, electric power and other fields. [0003] In related technologies, when specifically developing zirconia functional ceramic devices, zirconia is usually first granulated into ultra-fine powder, then pressed into a green body of a certain shape, put into a high-temperature furnace and sintered into porcelain, and finally through sealing, Oxygen sensors are prepared by welding and other processes. In this process, if the zirconia biscui...
