· NaSiO3

Sodium silicate (NaSiO3) is an inorganic ceramic compound commonly known as water glass, produced by fusing silica and sodium carbonate at high temperatures. It is widely used as a binder in foundry sand casting, a silicate-based adhesive for industrial bonding, and a chemical precursor in sol-gel synthesis of advanced ceramics and silica gels. Engineers select sodium silicate for cost-effectiveness, water solubility, and chemical stability, though it is typically combined with other phases or additives rather than used in pure form, and it is sensitive to carbonation and moisture in service environments.

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.
