Li4SiO4
ceramic· JVASP-10870· Li4SiO4
Lithium silicate (Li₄SiO₄) is an inorganic ceramic compound combining lithium oxide with silica, belonging to the silicate ceramic family. It is primarily investigated for advanced thermal and neutron applications, particularly as a tritium breeder material in nuclear fusion reactor blanket systems, where its ability to generate tritium fuel through neutron capture is critical for sustained fusion reactions. In thermal applications, lithium silicate ceramics are explored for high-temperature insulation and refractory uses, while also being studied for CO₂ absorption in carbon capture systems due to lithium's reactivity with acidic gases.

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.
