Abstract

PURPOSE:To improve the temperature and oxidation resistance by providing a boric acid compound coating on the surface at the opening of a getter. CONSTITUTION:A getter material 11 containing a barium-aluminium alloy powder and nickel powder is filled in an open metal ring getter container 12 where the surface is applied with a boric acid compound coating 13. A getter device having such structure is heated in the air then placed in an evacuated vacuum container which is applied with high frequency induction heating to perform the getter flash.
