· O7 K2 Sr1 Ta2

O7K2Sr1Ta2 is an experimental mixed-metal oxide semiconductor containing tantalum, strontium, potassium, and oxygen in a complex stoichiometric ratio. This compound belongs to the family of multivalent metal oxides, which are of interest in materials research for their potentially tunable electronic and optical properties. While not yet established in mainstream industrial production, materials in this compositional space are being investigated for solid-state electronics, photocatalysis, and functional ceramic applications where the combination of transition metals (tantalum) with alkaline-earth and alkali promoters can influence band structure and charge carrier behavior.

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.
