· Ce2 O4

Ce2O4 is a cerium oxide semiconductor compound that exists in the rare-earth oxide family, representing an intermediate oxidation state of cerium between CeO2 and Ce2O3. This material is primarily explored in research contexts for applications requiring mixed-valence cerium oxides, which exhibit unique oxygen-deficiency properties and redox activity not found in fully oxidized or reduced cerium phases. Industrial interest centers on catalysis, oxygen storage materials, and solid-state electrochemistry, where the variable oxidation state of cerium enables efficient oxygen transport and surface reactions at elevated temperatures.

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.
