Barium aluminate?
I see a lot of references in the literature to a "Barium Aluminate" that's used as a gas absorber in vacuum tubes. Apparently the barium on the surface binds with stray oxygen atoms, then the aluminum steals them, refreshing the surface for more absorption. There is no page for "barium aluminate", and I can't find a reference to the chemical formula for it. Anyone got a good reference?

vacuum characteristics of getter technology
The article doesn't give any information on the vacuum which can be obtained by getter and pumping speed, it seems to me that the best part of the information on getter is missing — Preceding unsigned comment added by 93.66.148.208 (talk) 07:40, 28 August 2019 (UTC)
