Na2Si2O5
ceramic· Na2Si2O5
Sodium disilicate (Na2Si2O5) is an inorganic ceramic compound belonging to the silicate family, commonly encountered as a component in glass formulations and industrial glass-ceramics rather than as a standalone engineered material. It appears primarily in soda-lime silicate glasses, glass coatings, and vitreous enamels where it acts as a flux to lower melting temperatures and improve workability during manufacturing. Engineers select silicate-based ceramics like this for applications demanding chemical durability, thermal stability, and cost-effectiveness, though the material is typically valued as a constituent phase rather than a discrete phase in final applications.

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.
