5 FAQs of Nano silica High purity nano colloidal silica/silica sol ludox SiO2 30nm

What is nano colloidal silica/silica sol (Ludox SiO2 30nm)? Nano colloidal silica, also known as silica sol or Ludox SiO2 30nm, is a stable aqueous dispersion of high-purity silicon dioxide (SiO2) nanoparticles with an average particle size of 30 nanometers. It is a milky liquid with high surface area, colloidal stability, and alkaline pH (typically 9–10), widely used in industrial and research applications due to its uniform particle distribution and non-agglomerating properties.

What are the primary applications of high-purity nano silica sol? This product is used in coatings, ceramics, electronics, and catalysts. It enhances abrasion resistance in surface coatings, acts as a binder in precision casting molds, serves as a polishing agent in semiconductor manufacturing, and stabilizes catalysts. Its high purity and small particle size ensure performance in demanding applications like optical fibers and advanced composites.

Why is the 30nm particle size significant? The 30nm size balances high surface area for reactivity and stability in dispersion. Smaller particles improve penetration into substrates, create uniform thin films, and enhance mechanical or optical properties in end products. This size minimizes sedimentation, ensuring long-term colloidal stability without compromising functionality in applications like coatings or electronics.

How should silica sol be stored and handled? Store in sealed containers at 5–30°C, avoiding freezing or prolonged heat. Shelf life is typically 12 months. Prevent contamination by avoiding contact with incompatible substances (e.g., acids, salts). Gentle mixing is recommended if settling occurs; vigorous shaking can cause foaming. Use clean equipment to maintain purity.

Is nano silica sol safe for handling and the environment? It is non-toxic but alkaline (pH ~9–10), requiring gloves and goggles to prevent skin/eye irritation. Ensure adequate ventilation. Disposal must comply with local regulations—neutralize with acid before wastewater discharge. While environmentally benign, avoid uncontrolled release to prevent pH disruption in ecosystems.
