· SrTlO3

Strontium titanate (SrTiO₃) is a perovskite ceramic compound combining strontium and titanium oxides, notable for its high dielectric constant and cubic crystal structure. While primarily a research material rather than a commodity engineering ceramic, SrTiO₃ is investigated for applications requiring high permittivity and thermal stability, particularly in capacitors, microwave devices, and electroceramics where its perovskite structure enables tunable electrical properties. It serves as a model system for studying ferroelectric and superconducting phenomena, and as a substrate material in thin-film electronics and advanced device development.

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.
