5 FAQs of Hydrophilic silica fume silica precipitation SIO2 silicon dioxide 99% nano silica from China

Hydrophilic silica fume, also known as precipitated silicon dioxide (SiO₂) or nano silica, is a high-purity (99%) ultrafine powder produced through chemical precipitation. It is widely used in industries like construction, electronics, coatings, and adhesives due to its small particle size, large surface area, and hydrophilic properties. Below are five common FAQs about this product:

**1. What is hydrophilic silica fume, and how is it produced?**
Hydrophilic silica fume is a nano-sized silicon dioxide powder synthesized via chemical precipitation. The process involves reacting sodium silicate with sulfuric acid or hydrochloric acid under controlled conditions, followed by filtration, washing, drying, and milling to achieve ultrafine particles. Its hydrophilic nature allows it to disperse easily in polar solvents like water.

**2. What are the primary applications of hydrophilic silica fume?**
This material is used as a reinforcing filler in rubber, plastics, and sealants; a rheology modifier in coatings and adhesives; a concrete additive to enhance strength and durability; a polishing agent in semiconductors; and an anti-caking agent in pharmaceuticals and food. Its high surface area improves mechanical and thermal properties in composites.

**3. Why choose hydrophilic silica fume over hydrophobic variants?**
Hydrophilic silica is ideal for water-based systems due to its compatibility with polar solvents. It forms stable suspensions, improves viscosity, and enhances bonding in aqueous formulations. Hydrophobic silica, treated with silanes, is better for non-polar systems like oils or organic polymers.

**4. How should hydrophilic silica fume be stored and handled?**
Store in a cool, dry place in tightly sealed containers to prevent moisture absorption. Use PPE (gloves, masks) during handling to avoid inhalation or skin contact. Although non-toxic, fine particles may irritate respiratory systems. Ensure proper ventilation in workspaces.

**5. What are the quality standards for Chinese hydrophilic silica fume?**
Reputable Chinese suppliers adhere to international standards like ISO 9001 and provide certificates of analysis (CoA) confirming purity (≥99%), particle size (10-50 nm), and surface area (150-400 m²/g). Buyers should verify batch-specific test reports for consistency and compliance with industry requirements.

This product offers cost-effective performance for advanced material applications, but quality varies among suppliers. Partner with certified manufacturers to ensure reliability.
