- 中文摘要: We describe a method for controlled preparation of nanostructural ZrO2-coated SiO2 particles by layer-by-layer assembly technique. ZrO2 colloids were synthesized by the sol-gel method. The samples were characterized by FIIR, DTA-TG, SEM, EDS, XPS and XRD techniques. The experimental results show that ZrO2 nanopowders on the surface of SiO2 particles are well distributed and compact; the amount of ZrO2 is increased with adding coating layers; the structure of this coating is tetragonal phase.
