· JVASP-34336· NaSO4

Sodium sulfate (Na₂SO₄) is an inorganic ceramic compound commonly encountered in salt form, used primarily as a filler, processing aid, and thermal storage material in industrial applications. In construction and materials processing, it serves roles in cement production, glass manufacturing, and as a component in thermal energy storage systems where its phase-change properties are leveraged. Engineers select sodium sulfate for cost-effectiveness in large-scale applications and its chemical stability, though its hygroscopic nature and relatively modest mechanical strength limit its use to non-structural or secondary 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.
