Silicon Oxide Nanopowder Water Dispersion (SiO₂, 25 wt%, 30 nm) is a water-based suspension of silicon dioxide (silica) nanoparticles with an average particle size of 30 nanometers. Here’s a detailed explanation:
1. Composition:
- Silicon Dioxide (SiO₂):
- A versatile material commonly found in quartz, glass, and sand.
- In nanoparticle form, it exhibits unique properties due to its small size and high surface area.
- Nanoparticles (30 nm):
- Ultra-fine particles with an average diameter of 30 nanometers.
- The nano-scale size enhances reactivity and surface interaction.
- 25 wt%:
- The dispersion contains 25% by weight of silicon dioxide nanoparticles, with the remaining 75% being water.
- Water-Based Dispersion:
- Uniformly suspended silica nanoparticles in water, making it easy to handle and integrate into various applications.
2. Key Properties:
- High Surface Area:
- The nano size provides a large surface area, enhancing reactivity and adsorption capabilities.
- Chemical Stability:
- SiO₂ is chemically inert and resistant to many chemicals, acids, and bases.
- Transparency:
- Silica nanoparticles are often transparent and suitable for optical applications.
- Hydrophilic Nature:
- Compatible with water-based systems due to its affinity for water.
- Thermal Stability:
- Maintains stability at high temperatures, making it ideal for high-heat applications.
- Dispersibility:
- Excellent dispersion stability in water, ensuring even distribution without agglomeration.
3. Applications:
- Coatings:
- Used in transparent, anti-reflective, or protective coatings for glass, lenses, and electronic displays.
- Polishing:
- A key component in precision polishing slurries for semiconductors, optics, and metals.
- Composites:
- Reinforces mechanical, thermal, and chemical properties in polymer and ceramic composites.
- Catalysis:
- Acts as a support material for catalysts, enhancing catalytic efficiency.
- Adsorption:
- Used in filtration and purification systems due to its high surface area and adsorptive properties.
- Biomedical Applications:
- In drug delivery, biosensors, and diagnostic tools due to its biocompatibility.
- Electronics:
- Insulating material in microelectronics or as a filler in thermal management systems.
- Paints and Inks:
- Improves durability, scratch resistance, and clarity in water-based formulations.
4. Advantages:
- Ready-to-Use:
- Pre-dispersed in water, eliminating the need for additional preparation steps.
- Environmentally Friendly:
- Water-based dispersion avoids hazardous organic solvents.
- Versatile:
- Applicable in a wide range of industrial and scientific fields.
- Enhanced Properties:
- Improves mechanical strength, thermal resistance, and chemical durability in composites and coatings.
5. Handling and Storage:
- Handling:
- Stir or shake the dispersion before use to ensure uniform distribution of nanoparticles.
- Avoid aerosolizing the suspension to prevent inhalation risks.
- Storage:
- Store in a cool, dry place away from direct sunlight.
- Protect from freezing or overheating, which can destabilize the dispersion.
- Safety:
- While SiO₂ is generally non-toxic, handle with care to avoid contact with skin, eyes, or inhalation of mist.
This water dispersion of silicon oxide nanoparticles is highly versatile, offering unique benefits such as high surface area, chemical stability, and ease of use. It is suitable for applications in coatings, composites, polishing, catalysis, and more.
