· SrCrO4

Strontium chromate (SrCrO4) is an inorganic ceramic compound and semiconductor material belonging to the chromate family, known for its yellow crystalline structure and moderate electrical conductivity. Historically used as a corrosion-inhibiting pigment in aerospace coatings and primer systems, it has become less common in new applications due to environmental and health concerns regarding hexavalent chromium compounds. Current research interest focuses on its potential in photocatalytic applications, thin-film electronics, and as a component in specialized ceramic formulations, though its industrial adoption remains limited compared to chromate alternatives with lower toxicity profiles.

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
