· JVASP-109164· Li4Mg

Li₄Mg is an intermetallic ceramic compound combining lithium and magnesium, representing a lightweight material in the lithium-metal family with potential applications in energy storage and structural systems. This compound is primarily of research and development interest rather than established industrial production; it exemplifies the class of lightweight ceramic intermetallics being investigated for high-performance applications where extremely low density combined with ionic or ceramic bonding characteristics are valued. Engineers would consider this material in early-stage projects targeting ultra-lightweight structural components or energy-related systems where conventional alloys are too dense, though material availability, processing methods, and mechanical property validation would be critical feasibility factors.

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.
