· Na4SiO4

Sodium silicate (Na₄SiO₄) is an inorganic ceramic compound belonging to the silicate family, commonly known in its hydrated forms as water glass or liquid glass. It is primarily used in industrial applications requiring strong adhesive bonding, chemical resistance, or as a precursor for sol-gel synthesis and specialty ceramic production. This material is valued in construction, refractory systems, and chemical processing for its ability to form durable inorganic binders and its role as a starting material for advanced silicate-based ceramics and coatings.

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.
