· CaTiO2

Calcium titanate (CaTiO₃) is a ceramic oxide compound belonging to the perovskite family of materials, characterized by a calcium-titanium-oxygen crystal structure. It is primarily used in electronic and photocatalytic applications, including dielectric ceramics for capacitors, pigments, and photocatalytic water treatment systems. Calcium titanate is valued for its chemical stability, thermal resistance, and photocatalytic properties under UV exposure, making it an attractive alternative to more toxic photocatalytic materials in environmental remediation, though it remains less common in mainstream engineering than related compounds like barium titanate.

Regulatory Screening

Environmental

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.
