How Induction Getter Firing Works

A getter is heated with induction and the activated material oxidizes and absorbs oxygen and other impurities, which increases the vacuum tube’s life.

How Induction Getter Firing Works

A getter is heated with induction and the activated material oxidizes and absorbs oxygen and other impurities, which increases the vacuum tube’s life.

A getter is a device containing powdered metal that strongly reacts to oxygen. In a variety of vacuum tubes including light bulbs, television sets, cathode ray tubes and vacuum-insulated tubes, barium is often the element used as a getter.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide, carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
