Glass welded ceramic composite vacuum plate with getter and production method thereof
The invention discloses a glass welded ceramic composite vacuum plate with a getter. The ceramic composite vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the panel is made from a ceramic plate or a ceramic tile, the panel and/or the connecting layer are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity at barometric pressure, the vacuum cavity is a closed cavity formed by carrying out glass welding at constant temperature and high temperature and sealing at constant pressure to a low carbon steel plate; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a support and a getter are arranged in the vacuum cavity. A production method of the ceramic composite vacuum plate with the getter provided by the invention is simple in process, the air-tightness of the ceramic composite vacuum plate with the getter can be effectively ensured, the service life of the ceramic composite vacuum plate with the getter can be prolonged, and the strength, heat insulation, sound insulation and fire resistance can be improved.
