GETTER PRECURSORS FOR HERMETICALLY SEALED PACKAGING

摘要

hermetically sealed package of the present invention includes the getter precursor is located in the interior region of the package. Comprises an anion and an alkali oxide or alkaline earth metal cation-non-getter precursor is arranged to be such that thermal decomposition of the oxidation state of the cations changes to zero.
