ABSTRACT:
The present invention provides a getter material configured by a pressed powder mixture comprising Ba—Al alloy powder and Ni powder, wherein when the pressed powder mixture is heated in a vacuum atmosphere or an inert gas atmosphere, a temperature at which an exothermic reaction starts is ranging from 750° C. to 900° C. According to this getter material, since the temperature at which the pressed powder mixture starts the exothermic reaction is set within a range from 750° C. to 900° C., there can be provided a getter material and an evaporation type getter device capable of suitably controlling an evaporation amount of getter components under a stable condition, and is excellent in responsiveness because a time ranging from a starting time of heating the getter material to a starting time of evaporation of the getter components can be shortened. In addition, the metal container to be filled with the getter material is free from deformation and melting, and a heat-evaporation process time of the getter material can be shortened, so that there can be provided the evaporation type getter device excellent in responsiveness because a time required for the electron tube to attain to a predetermined vacuum degree can be also shortened.
