Strontium chromate

Description:
Strontium chromate, with the chemical formula SrCrO4 and CAS number 7789-06-2, is an inorganic compound characterized by its bright yellow color and crystalline structure. It is a strontium salt of chromic acid and is primarily used as a pigment in paints and coatings due to its excellent opacity and durability. Strontium chromate is known for its high stability and resistance to heat, making it suitable for various industrial applications. However, it is important to note that strontium chromate is classified as a hazardous substance; it contains hexavalent chromium, which is toxic and poses environmental and health risks. As such, proper handling and disposal procedures are essential to mitigate exposure. In addition to its use in pigments, strontium chromate has applications in corrosion resistance and as a chemical intermediate in various chemical processes. Its solubility in water is relatively low, and it can react with acids to release chromium ions, which can further contribute to its toxicity.
