Description and Uses
Barium chromate has been found to be useful in many capacities. It is an oxidizing agent, making it useful as a burn rate modifier in pyrotechnic compositions. It is especially useful in delay compositions such as delay fuses. Barium chromate is used as a pigment, oxidizing agent, colorant in glass, and sulfate scavenger in chromium electroplating baths, ceramics, and porcelain. It acts as a corrosion inhibitor in jointing pastes and metal primers. Further, it is used in fuses, safety matches, ignition control devices and high-temperature batteries. In addition to this, it is used as a carrier for the chromium ions and useful as a burn rate modifier in pyrotechnic compositions. It is involved as a catalyst in the alkane dehydration reaction.
