Abstract:A unified approach, HGCP process was applied to produce various metal oxide nanoparticle dispersion with low cost. The process involved achieving instantaneous molecular mixing for metal salts and precipitant reactants by using HGCP reactor to control nucleation, particle growth and then in-situ modification of the formed nanoparticles to prevent particle-particle agglomeration. The obtained zinc oxide (ZnO) nanoparticle dispersion can keep transparent even at solid content of 50 wt%, with the primary particle size of 5-10 nm, and the secondary particle diameter of about 30 nm. The crystal structure of ZnO was almost exclusively related to a hexagonal wurtzite crystalline system. The obtained antimony doped tin oxide (ATO) mono-dispersed particles were of the primary particle size of 7-15 nm, and secondary particle diameter of about 50 nm. The crystal structure of ATO was related to tetragonal cassiterite crystalline system. The as prepared film containing ZnO and ATO nanoparticles for glass could realize cut-off most UV, high transparency for visible light as well as strong absorption of infrared light. These of interesting characters endow the metal oxide nanoparticle dispersion in promising applications such as smart window, solar collector, optical devices, etc.
