· Cu5Ta11O30

Cu5Ta11O30 is a mixed-metal oxide semiconductor composed of copper and tantalum in a complex perovskite-related crystal structure. This is primarily a research material investigated for photocatalytic and electronic applications rather than a widely commercialized engineering material. The material is notable within the broader family of copper-tantalum oxides for potential use in water purification, environmental remediation, and optoelectronic devices, where its layered structure and mixed-valence metal centers offer advantages over single-metal oxide semiconductors in charge separation and visible-light activity.

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.
