BaCrO3

Barium chromate (BaCrO₄) is an inorganic ceramic compound with semiconductor properties, belonging to the chromate mineral family. It is primarily used in pigmentation, corrosion inhibition coatings, and specialized ceramic applications where its yellow-orange coloration and chemical stability are valued; it also sees research interest in photocatalytic and electrochemical applications due to its band gap characteristics. Engineers typically select this material for demanding environments requiring excellent chemical resistance and thermal stability, though its use is increasingly restricted in some regions due to chromate toxicity concerns, making it less preferred than safer alternatives in consumer-facing applications.
