Sodium Silicate – High Purity Water Glass

Sodium Silicate (Na₂SiO₃) is a colorless to light gray, water-soluble compound formed by the fusion of silica (SiO₂) and sodium carbonate (Na₂CO₃) at high temperatures. It is available as a liquid solution or in powder/granular form, often referred to as liquid glass for its transparent, viscous appearance when dissolved.

Due to its strong alkaline nature, excellent adhesive and binding properties, and ability to form silica gel, Sodium Silicate is widely utilized in:

• Detergents & Soaps – as a builder or corrosion inhibitor

• Ceramics & Refractories – for bonding and thermal stability

• Paper Industry – for sizing and coating

• Water Treatment – as a deflocculant or coagulant

• Construction & Foundry – as a binder in molds and concrete hardeners

At Cavin Resource, our high-purity Sodium Silicate meets industrial performance standards with customizable ratios of SiO₂ to Na₂O to match specific process requirements.

⚙️ Production Method

Thermal Fusion and Dissolution Process

1. High-purity sand (SiO₂) is fused with sodium carbonate (Na₂CO₃) in a furnace

2. The resulting glassy solid is cooled and ground or dissolved in water to produce liquid sodium silicate

3. Liquid is adjusted to specific viscosity and molar ratio specifications (e.g., 2.0–3.5 SiO₂:Na₂O)
