Product Features (Nano Silica)
- High purity, small particle size with uniform distribution, large specific surface area, strong surface activity, high temperature resistance, and low bulk density;
- Excellent dispersibility, suspension, vibration liquefaction, and thixotropy, with both reinforcing and thickening effects;
- Surface contains a large number of unsaturated bonds and hydroxyl groups; due to oxygen deficiency on the surface, it deviates from the stable siloxane structure, resulting in high light reflectivity, low bulk density of active powder, and easy dispersion;
- Superior optical performance: Reflectivity reaches 70~80% for short-wave UV (200~280nm), 80~88% for long-wave UV (280~400nm), over 85% for visible light (400~800nm), and over 70% for near-infrared (800~1350nm).
Brief Introduction
Atomfair Silica (SiO₂) is available in multiple specifications (10nm~40μm), including nano/micron grades and spherical/spherical-like morphologies. It combines high purity, excellent dispersibility, and superior optical performance, serving as a multifunctional powder material for scientific research scenarios such as material modification and optoelectronic devices.
