BARIUM CHROMATE AR
Barium Chromate is a yellow-colored, sand-like powder. It is used in artists' colors, in coloring glass and ceramics, as a corrosion inhibitor, and in safety matches.
Barium, as a metal or when alloyed with aluminium, is used to remove unwanted gases (gettering) from vacuum tubes, such as TV picture tubes.
The barium mineral, benitoite (barium titanium silicate), occurs as a very rare blue fluorescent gemstone, and is the official state gem of California.
Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure.[5]: 2 The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray layer containing the oxide.
