Na2O
ceramic· Na2O
Sodium oxide (Na2O) is a basic ceramic compound and a key constituent of soda-lime silicate glasses rather than a standalone engineering material. It functions as a flux and network modifier in glass compositions, lowering melting temperatures and improving workability while affecting the final glass properties. Na2O is encountered by engineers primarily through its role in common glass formulations, optical coatings, and ceramic glazes, where it enables cost-effective manufacturing of consumer and industrial glass products.

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.
