· N1 O2 Na1

Na₂O (sodium oxide) is an ionic ceramic compound belonging to the oxide family, commonly encountered as a constituent phase in glass and ceramic systems rather than as a standalone engineering material. This compound is primarily significant in materials science as a glass former and flux in silicate ceramics, where it lowers melting temperatures and modifies glass properties; it is rarely specified as a primary phase in structural applications due to its hygroscopic nature and reactivity with atmospheric moisture. Engineers encounter sodium oxide most often as a controlled dopant or secondary phase in optical glasses, enamels, glazes, and advanced ceramics, where its role is to tune thermal expansion, refractive index, and processing behavior rather than to serve as the primary load-bearing constituent.

Export Control

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.
