· Ca4 Y2 Bi2 O10

Ca₄Y₂Bi₂O₁₀ is an oxide ceramic semiconductor composed of calcium, yttrium, and bismuth—a mixed-metal oxide system that belongs to the family of rare-earth and post-transition metal compounds. This is primarily a research material studied for its potential in photocatalytic and optoelectronic applications, particularly where bismuth-containing oxides offer advantages in visible-light absorption and charge separation. The yttrium and calcium dopants modify the band structure and lattice properties, making this compound of interest in emerging photocatalysis, environmental remediation, and potentially photovoltaic or scintillation detector contexts where bismuth oxides are explored as alternatives to lead-based formulations.

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.
