The Barium Chromate offered by us is used as a carrier for the chromium ions, use of barium chromate as a Sulfate scavenger in chromium electroplating baths, used as an oxidizing agent, making it useful as a burn rate modifier in pyrotechnic compositions, used as a corrosion inhibitive pigment when zinc-alloy electroplating surfaces, used in the composition of a catalyst for alkane dehydrogenation. Barium can also be used to colour paints. The pigment known as lemon yellow often contained barium chromate mixed with lead Sulfate. Due to its moderate tinting strength lemon yellow was not employed very frequently in oil painting. Barium Chromate is available in the form of Yellow powder packed in 25kg, 50kg HDPE Bag. We can offer it in many grades as per the application needs in different industry sectors.
