· C1 O5 Bi2

Bismuth pentoxide (Bi₂O₅) is an oxide semiconductor compound belonging to the bismuth oxide family, which exhibits mixed-valence behavior and ionic-electronic conductivity. This material is primarily investigated for photocatalytic applications, oxygen ion conductors in solid oxide fuel cells, and gas sensing devices, where its layered crystal structure and band gap properties enable selective chemical detection and energy conversion. Bismuth oxide compounds are valued alternatives to traditional semiconductor oxides because of their lower toxicity compared to lead-based materials, their tunable electronic properties through compositional variation, and their potential for room-temperature operation in sensing applications.

Export Control

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.
