Title:
CERAMIC JOINING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/051076
Kind Code:
A1
Abstract:
A ceramic joining device, comprising a working furnace (100), a clamping mechanism (130), a vacuum interface (140), and a heater (150). A furnace cavity (111) is formed in the working furnace (100) and is used for accommodating a target material (300). The clamping mechanism (130) is located in the furnace cavity (111) and is used for fixing samples to be joined (400). The vacuum interface (140) is communicated with the furnace cavity (111) and is configured to be joined to a vacuum generator, so that the furnace cavity (111) is in a vacuum environment. The heater (150) is joined to the working furnace (100) and is used for heating the target material (300) in the furnace cavity (111) to a preset temperature. When the vacuum degree in the furnace cavity is lower than the saturation vapor pressure of the target material, the target material at the preset temperature can be gathered to said samples in the form of steam, so that a gas permeation reaction occurs in a gap of a ceramic to form a joining layer, and the joining between said two samples is realized, without filling a joining position with a joining material in advance. Therefore, the processing steps of welding of said samples are simplified, and the processing difficulty is reduced.
