· Li19Si6

Li19Si6 is a lithium silicide ceramic compound representing an intermetallic phase in the lithium-silicon system. This material exists primarily as a research composition rather than a commercialized engineering material, studied for its potential in energy storage, solid electrolyte, and lightweight structural applications where lithium's low density and high electrochemical activity could provide advantages. The lithium-rich silicide family is of particular interest in next-generation battery systems and advanced ceramic matrices, though Li19Si6 itself remains in exploratory development rather than established industrial production.

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.
