· 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.
