· JVASP-118644· Na2AlO2

Sodium aluminate (Na₂AlO₂) is an inorganic ceramic compound formed from sodium and alumina, commonly produced as a powder or dissolved in aqueous solutions. It serves primarily as a chemical intermediate in water treatment, cement chemistry, and alumina refining processes, where its strong alkalinity and aluminum solubility make it valuable for coagulation, pH adjustment, and industrial synthesis rather than as a structural ceramic material itself.

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.
