Li3Mg8Si4
ceramic· JVASP-154536· Li3Mg8Si4
Li3Mg8Si4 is a quaternary ceramic compound combining lithium, magnesium, and silicon—a lightweight, multi-phase material that sits at the intersection of intermetallic and ceramic chemistry. This is primarily a research compound rather than a commercial material; it belongs to the family of lightweight structural ceramics and magnesium-based composites being explored for applications requiring low density combined with stiffness. The material's potential lies in aerospace and automotive weight reduction programs, though industrial adoption remains limited pending further development of processing methods and long-term performance validation.

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.
