Abstract
A getter body for use in encapsulated electrical components is of the type consisting of a powder mixture which has been compressed into tablet form. The powder mixture contains in addition to traditional getter material such as activated carbon, zeolite or the like, aluminum stearate and a binder containing a synthetic such as a polyamide. The getter body is produced in several sequential steps. The getter material is mixed with a polycarbonate or a water glass solution, which is then dried and then pulverized. To this first powder is added the aluminum stearate and the binder containing a synthetic. The resulting powder may then be dried and is then pressed into tablets. The tablets may then be heat-cured and are then surfaced polished. The resulting tablets have good abrasion resistance without a noticeable loss in the getter effectiveness.
