Barium is a soft, silvery-white metal that was discovered in 1772. It has a medium density and good electrical conductivity. While ultrapure barium is difficult to prepare, barium and barium alloys are commonly used to remove unwanted gases from vacuum tubes.

Barium is a soft, silvery-white metal. It has a medium specific weight
and good electrical conductivity. Ultrapure barium is very hard to
prepare, and therefore many properties of barium have not been
accurately measured yet. Barium, as a metal or when alloyed with
aluminium, is used to remove unwanted gases (gettering) from vacuum
tubes, such as TV picture tubes.](https://image.slidesharecdn.com/bariojoseangelguillenromero3b-130506160845-phpapp01/85/Bario-jose-angel-guillen-romero-3-b-1-320.jpg)
