CAS 10294-40-3: Barium chromate

Barium chromate has been found to be useful in many capacities. often the compound is used as a carrier for the chromium ions. 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. It is also used in the composition of a catalyst for alkane dehydration.

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.

Barium chromate is a compound that is used as an oxidation catalyst in industrial processes. It is a white solid with a metallic luster and a high melting point. When barium chromate is heated, it decomposes to form barium oxide, carbon dioxide and oxygen gas: br> BaO + CO2 + O2 → BaO + CO br> Barium chromate can be prepared by reacting barium hydroxide with chromic acid or by heating the combination of calcium stearate, sodium carbonate and hydrochloric acid. The linear regression analysis of the activation energies for the oxidation reactions has been shown to be dependent on the concentration of polycarboxylic acid in the test samples, which may be due to an increase in hydrogen ion concentration. This increase in hydrogen ion concentration leads to increased rates of reaction between barium ions and polycarboxylic acids.
