· Na2SO4

Sodium sulfate (Na2SO4) is an inorganic salt ceramic compound commonly encountered in two hydrated forms: the decahydrate (Glauber's salt) and anhydrous form. While not a structural ceramic in the traditional sense, it functions as an important industrial chemical with applications in thermal energy storage, chemical processing, and material synthesis where its phase-change properties and chemical stability are exploited. Engineers select sodium sulfate for its reversible hydration behavior, cost-effectiveness, and environmental benignity compared to synthetic phase-change materials, though its relatively low energy density and corrosive nature in hydrated form require careful system design.

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.
