Abstract
Compositions containing getter material and getter devices for which gettering activity can be activated at applied temperatures that are lower than those temperatures required for activating the getter material alone are disclosed. In one aspect, a getter composition that includes a getter component and an activator component is provided. The getter component is selected from the group consisting of evaporable and non-evaporable getter materials. The activator component is effective to heat said getter material to a temperature greater than about 500° C. when said activator material is heated to a temperature of between about 280° C. and about 500° C. In some embodiments, the activator component is effective to bring the temperature of the getter material to greater than about 1,000° C. These materials can be used in devices and locations for which low applied activation temperatures are required.
