application area  
Zirconium aluminum alloy powder is widely used in vacuum electronic devices, creating a good working environment for the devices, stabilizing their characteristic parameters, and having an important impact on the performance and service life of the devices 
① Improving the vacuum degree of vacuum devices (above Dapa) in a short period of time, eliminating residual and re released gases during the exhaust sealing and aging process of the devices, is beneficial for shortening the exhaust time; 
② Maintain a certain degree of vacuum during the storage and operation of the device; 
③ The absorption device effectively protects sensitive components such as cathodes from sudden gas release during start-up and abnormal operation. 
classification 
Non evapotranspiration type absorbent 
Zirconium aluminum alloy powder belongs to the non evaporative type of absorbent, which is made of absorbent materials with high evaporation temperatures. This type of inhaler does not require evaporation, but must be activated to have inhalation performance. Activation is the process of subjecting the inhaler to appropriate heating treatment to give it strong suction capacity. During the activation process, the gas released by the inhaler is either extracted by a vacuum pump or absorbed by an evaporative inhaler. After activation treatment, non evaporative absorbers can absorb a large amount of air at working temperature. Non evaporative absorbers absorb gas inside pipes through surface adsorption of gas and diffusion of gas into the interior of the absorber. The commonly used suction materials for non evaporative absorbers include titanium, zirconium, tantalum, thorium, etc. Among them, zirconium based absorbers are the most commonly used. Such as zirconium aluminum 16 absorber, etc. 
application area  
Zirconium aluminum alloy powder technology has the characteristics of economy, simplicity, effectiveness, and durability for obtaining a good vacuum atmosphere inside the tube. It plays a significant role in the development and production of long-life, highly reliable, and high-performance electric vacuum devices. It is not only widely used in electric vacuum devices such as amplifying tubes, power emitting tubes, black and white or color television tubes, oscilloscopes, camera tubes, traveling wave tubes, fluorescent lamps, and high-pressure discharge lamps, but also in the manufacturing of photocathodes, atomic reactors, controllable nuclear fusion devices, gas lasers, purification of rare gases, and high vacuum acquisition.
