· JVASP-116713· Al5O8

Al₅O₈ is an aluminum oxide ceramic compound representing a mixed-valence alumina phase distinct from the common corundum (Al₂O₃) form. This material is primarily encountered in research and specialized industrial contexts where its unique crystal structure and thermal properties offer advantages in refractory applications, ceramic matrix composites, and high-temperature structural ceramics. Its selection over conventional alumina depends on specific thermal cycling resistance and phase stability requirements in demanding environments.

Regulatory Screening

Environmental

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.
