· Al4 Bi6 O18

Al₄Bi₆O₁₈ is an oxide semiconductor compound combining aluminum and bismuth oxides in a layered perovskite-related structure. This is primarily a research material investigated for photocatalytic and optoelectronic applications, rather than an established industrial material; the bismuth oxide component confers visible-light absorption characteristics absent in pure aluminum oxides, making it of interest for environmental remediation and energy conversion research.

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.
