Abstract
A getter comprising a calcium-aluminum compound including about 39% to about 43% calcium by weight produces a calcium vapor when sufficiently heated. The calcium vapor can condense to form a calcium film on an inside surface of a sealed evacuated enclosure such as a CRT to getter reactive species from the enclosed volume. The calcium-aluminum compound, preferably CaAl powder, can be mixed with either nickel powder, titanium powder, or both.
