A Microwave Oven Magnetron Yttrium Rhenium Tungsten Electrode and its Preparation Process Inventions

Microwave oven magnetron electrode, electron emitters , is an integral part of the interaction space . The performance of the magnetron cathode operating characteristics and lifetime great impact , is considered the heart of the magnetron . People in order to improve the function of the electron emission cathode , in a pure tungsten material added thorium , but this system is made ​​of alloy cathode product exists brittle at room temperature and high temperature brittleness of congenital defects has not yet solved . Magnetron cathode lead in the production, transport and use occurred during uncontrolled rupture , resulting in failure of the magnetron . Seriously affect the reliability of the product , increasing the manufacturing cost. In addition , radioactive thorium , thorium added as the main raw material , in the smelting , production, transport and use, the environmental pollution , the final product made ​​of the contact potential human health is also adversely affected, and Th half-life of 1.39 × 10 10 years, it is difficult to recycle , and its discarded products constitute a threat of pollution to the environment , so while China is currently the world's 100% commitment microwave oven magnetron production of rare earth thorium as an extremely important strategic resource , nuclear power can be used for clean energy manufacturing , therefore, from the viewpoint of the rational use of resources , in the microwave , to provide an alternative to the existing thoriated tungsten cathode magnetron has become an important research topic in the field .

Rhenium Yttrium tungsten electrode microwave oven magnetron and its preparation process object of the invention is to solve the inadequacy of existing technology to provide not only a good product performance , long life , low production costs , and no radiation in the microwave magnetron tungsten rhenium yttrium cathode . Yttrium tungsten rhenium microwave oven magnetron electrode and its preparation process is another object of the invention is to provide a tungsten- rhenium yttrium said microwave oven magnetron cathode preparation .
