Sodium Silicate Powder

الوصف

Sodium silicate, often referred to as water glass or liquid glass, is a compound composed of sodium oxide (Naâ‚‚O) and silica (SiOâ‚‚). It exists in various forms, but the most common is a glassy, colorless solid or a thick, syrupy liquid. Its chemical formula is usually represented as Naâ‚‚SiO₃ or (Naâ‚‚O·SiOâ‚‚), depending on the ratio of sodium to silica.

Key Properties:

 • Appearance: Transparent, colorless, or slightly colored; available in solid or liquid forms.
 • Solubility: Soluble in water, forming an alkaline solution.
 • Alkalinity: Sodium silicate solutions are highly alkaline, with a pH typically ranging from *0 to *3.
 • Viscosity: Varies from low to very high depending on the concentration and temperature.

Applications:

 • Adhesive: Used as a binder in cement, cardboard, and paper products.
 • Sealant: Serves as a sealing agent in automotive repairs (e.g., fixing leaks in engine blocks).
 • Detergents: Used as a buffering agent and corrosion inhibitor.
 • Fireproofing: Provides fire resistance when applied to materials like wood or textiles.
 • Water treatment: Acts as a coagulant in water treatment processes to remove suspended particles.

Sodium silicate is widely used in various industries, including construction, automotive, textile, and ceramics.
