ceramic· JVASP-91438· Ca2ThSi8O20
Ca₂ThSi₈O₂₀ is a thorium-bearing silicate ceramic compound belonging to the family of rare-earth and actinide silicates. This material is primarily of research interest rather than in widespread industrial production, studied for its potential in nuclear waste immobilization and actinide host matrices due to thorium's presence as a fuel-cycle element. The compound's significance lies in its chemical stability and potential resistance to radiation damage, making it relevant to the nuclear materials and ceramic science communities as a candidate waste form or transmutation target.

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.
