Claim 12
Dependent Claim
42 words
A getter device comprising a barium alloy, a metal capable of reacting exothermically admixed with the barium alloy and having an organosilane coating, wherein the weight ratio of the barium alloy to the metal capable of reacting exothermically is 1:4 to 4:1.
Claim 13
Dependent Claim
42 words

Claim 14
Independent Claim
50 words
A method of manufacturing an exothermic getter device comprising the steps of pressing a pulverulent mixture comprising a barium-aluminum alloy together with a metal capable of reacting exothermically with the barium-aluminum alloy into a holder, then exposing the pulverulent mixture in the holder to an organosilane, thereby producing a coating.
Claim 15
Independent Claim
50 words
A method of manufacturing an exothermic getter device comprising the steps of pressing a pulverulent mixture comprising a barium-aluminum alloy together with a metal capable of reacting exothermically with the barium-aluminum alloy into a holder, then exposing the pulverulent mixture in the holder to an organosilane, thereby producing a coating.
