NaAlO3

ceramic

· NaAlO3

Sodium aluminate (NaAlO₂·2H₂O or related phases) is an inorganic ceramic compound containing sodium and aluminum oxides, commonly produced as a white powder or aqueous solution. It serves primarily as a raw material in alumina refining, construction chemistry, and specialty chemical synthesis rather than as a final-form structural ceramic. Its main industrial value lies in its role as a precursor for aluminum hydroxide production, a binder in refractory systems, and as an activator in alkali-activated cement formulations—making it important for engineers working with advanced concrete, geopolymers, and chemical processing 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.
