Nucleation and fractal growth of zirconium oxo-alkoxy nanoparticles at the induction stage of sol–gel process


Monodispersed zirconium oxo-alkoxy nanoparticles are synthesized via a sol–gel method in a rapid micromixing reactor with in situ particle size measurements. The nucleated nanoparticles of 4.7 nm diameter are free from impurities and conserve high chemical activity. They can be associated in 1D fractals. These nanoparticles can form high optical-quality coatings on hydrophilic substrates.
