· Sr2Ti0.8Nb0.2O4

Sr2Ti0.8Nb0.2O4 is a mixed-metal oxide ceramic compound combining strontium, titanium, and niobium in a perovskite-related crystal structure. This is a research-phase material synthesized to explore how niobium doping modifies the functional properties of strontium titanate—a well-established ceramic platform. The material is investigated primarily for solid-state ionics, electrochemical applications, and high-temperature functionality where the substitution of niobium is expected to alter electrical conductivity, thermal behavior, and phase stability compared to the parent Sr2TiO4 compound.

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.
