硅酸钠 - 高纯水玻璃

sodium silicate suppliers

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

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

• 水处理 – 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.

⚙️ 生产方式

Thermal Fusion and Dissolution Process

1. 高纯度 sand (SiO₂) is fused with sodium carbonate (Na₂CO₃) in a furnace

2. 由此产生的 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)
