Abstract

PURPOSE: To produce a getter agent which adsorbs org. gases well and does not cause scattering of powder by coating the other surface except one surface of a plate-like alumina molding with water glass and firing the same.
CONSTITUTION: Bayer's aluminum hydroxide or the like consisting essentially of Al2O3, SiO2, etc. is molded to form an alumina molding 1. Thence, the other surface except the surface 1a functioning as a getter out of the surfaces of said molding 1 is coated with a water glass layer 2 and is fired at about 400W 700°C, whereby a getter agent 3 is formed. An adhesive 4 is coated on the outer side of the water glass later 2 for adhering and fixing the getter agent 3. Hence, the percolation of the adhesive 4 into the alumina material 1 and the degradation of the getter function are obviated. When the getter agent 3 is used by adhering and fixing the same to a required place of a switch, a relay, etc., the production of the powder is prevented by the layer 2 and the degradation in the function of the switch, the relay, etc. is prevented.
