Solid sodium silicate is a white or slightly pale-blue granular substance. It dissolves readily in water, forming an alkaline solution with viscous properties and excellent gelling performance.
Product Details
Product Feature Characteristics:
Solid sodium silicate, with the molecular formula Na 2O.nsiO2 Commonly known as water glass, it is a white or slightly pale-blue granular substance. It dissolves easily in water, forming an alkaline solution with both adhesive properties and excellent gelling capabilities. Additionally, sodium silicate exhibits high resistance to fire, acids, and corrosion.
Product Overview:
Our company produces solid sodium silicate products that appear nearly transparent (with a slight pale blue tint). We offer three distinct forms: dry-cast jelly-like blocks, crushed glassy solid strips, and granular particles created through water-quenching. These products are manufactured by high-temperature melting of pure soda ash and quartz sand. We provide two high-modulus grades—S-350 (modulus range: 3.41–3.6) and S-330 (modulus range: 3.1–3.4)—as well as one medium-modulus grade, S-280 (modulus range: 2.6–3.0), and one low-modulus grade, S-250 (modulus range: 2.2–2.5). Additionally, we can customize the modulus according to specific customer requirements.
Main applications of the product:
Widely used in industries such as casting, daily chemical detergents, acid- and alkali-resistant construction materials, refractory products, cement waterproofing and solidification, and welding electrode manufacturing. It is also employed as a chemical raw material in the production of white carbon black, silica gel, silica sol, molecular sieves, and other products.
