NON-EVAPORABLE GETTER COMPOSITIONS WHICH CAN BE REACTIVATED AT LOW TEMPERATURE AFTER EXPOSURE TO REACTIVE GASES AT A HIGHER TEMPERATURE

摘要

Compositions containing a mixture of non-evaporable getter alloys are described. The compositions, after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a second temperature that is lower than the first one.
