Strontium chromate refers to a chemical compound that is a light yellow powder or granular solid and insoluble in water. Its chemical formula is srcro4. Strontium chromate is a crystalline and inorganic compound. When it is heating, toxic chromium fumes are emitted. It is a strong oxidizing agent and extremely corrosive, and has many applications. Strontium chromate is a common corrosion inhibitor. It provides excellent corrosion resistance for metal substrates, particularly aluminum substrates. It is also used as a pigment, a protective coating, and in pyrotechnics. It has applicability as an anti-corrosive primer for zinc, magnesium, aluminum and alloys used in aircraft manufacturing.
