· LiAlON2

LiAlON₂ is a lithium aluminum oxynitride ceramic compound that combines lithium, aluminum, oxygen, and nitrogen in a mixed-valence crystal structure. This material belongs to the family of oxynitride ceramics, which are primarily of research and developmental interest for high-performance applications requiring thermal stability, hardness, and chemical resistance. Notable in advanced ceramic applications where conventional oxides or nitrides reach performance limits, LiAlON₂ is being explored for wear-resistant coatings, high-temperature structural components, and specialized optical or electronic applications, though industrial adoption remains limited compared to established ceramics like alumina or silicon nitride.

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.
