Nano Silicon Dioxide

Updated: 2026-09-15

Overview

Nano Silicon Dioxide is a high-purity nanomaterial composed of silicon and oxygen atoms arranged in a three-dimensional network. With a purity of 99.99%, it is widely used in advanced industrial applications due to its nanoscale particle size (typically 1-100 nm) and high surface area. This material is synthesized through methods such as sol-gel processes, flame pyrolysis, or chemical vapor deposition, ensuring consistent quality and performance. Its unique properties, including thermal stability, mechanical reinforcement, and chemical inertness, make it a versatile additive in various industries. Nano Silicon Dioxide is particularly valued for its ability to enhance the durability, strength, and functionality of composite materials, coatings, and electronic components.

Physical and Chemical Properties

Nano Silicon Dioxide exhibits a range of exceptional physical and chemical properties. Its high surface area (up to 500 m²/g) and small particle size contribute to its reactivity and reinforcing capabilities. The material is chemically inert, resisting reactions with most acids, alkalis, and solvents, which makes it suitable for harsh environments. Thermally, it is stable up to 1600°C, making it ideal for high-temperature applications. Its low density and high porosity also allow for lightweight yet strong composite materials. Additionally, its optical properties, such as transparency in the visible spectrum, enable uses in coatings and films where clarity is essential.

Main Applications

Nano Silicon Dioxide is utilized across multiple industries due to its versatility. In electronics, it serves as a dielectric material in semiconductors and as a filler in printed circuit boards. In coatings, it enhances scratch resistance, UV protection, and adhesion. The pharmaceutical industry uses it as a flow agent in tablets and as a carrier for drug delivery systems. In composites, it improves mechanical properties such as tensile strength and elasticity. Other applications include adhesives, sealants, and catalysts, where its high surface area and reactivity are advantageous.

Safety and Storage

While Nano Silicon Dioxide is generally considered safe, precautions are necessary to handle it properly. Inhalation of nanoparticles can pose respiratory risks, so use in well-ventilated areas or with appropriate respiratory protection. Skin contact should be minimized with gloves and protective clothing. Storage requires a dry, cool environment to prevent moisture absorption, which can affect performance. Containers should be sealed tightly and labeled clearly. Safety Data Sheets (SDS) should be consulted for specific handling and disposal guidelines to ensure compliance with local regulations.

B2B Procurement Guide

When procuring Nano Silicon Dioxide, prioritize suppliers with certifications such as ISO 9001 to ensure quality. Key specifications to verify include purity (99.99%), particle size distribution, and surface treatment (hydrophilic or hydrophobic). Request a Certificate of Analysis (COA) and SDS for compliance and safety. Bulk purchases may offer cost savings, but ensure proper storage conditions to maintain material integrity. Sample testing is recommended to confirm performance in your specific application. Establish long-term partnerships with reliable suppliers to secure consistent quality and supply chain stability.
