· JVASP-52849· Al5HO8

Al5HO8 is an aluminum oxide-based ceramic compound, likely a hydroxide or oxyhydroxide phase of alumina. This material belongs to the family of alumina ceramics, which are widely valued for their hardness, thermal stability, and chemical resistance. The specific Al5HO8 composition suggests a hydrated or partially hydroxylated aluminum oxide phase that may offer different sintering behavior or surface properties compared to conventional α-alumina, making it of interest in advanced ceramic processing and specialized coating applications.

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.
