· JVASP-52817· LiAl3Si9N14O2

LiAl3Si9N14O2 is a lithium aluminosilicate nitride ceramic belonging to the family of oxynitride ceramics, which combine the structural benefits of nitrides with oxide stability. This material is primarily of research and developmental interest, explored for high-temperature structural applications where conventional ceramics face thermal or mechanical limitations, particularly in aerospace and advanced engine systems where lightweight, thermally stable ceramics are critical.

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.
