Preparation of homodispersed nano zirconia

摘要: Abstract Direct precipitation was used to prepare nano zirconia in this experiment. The influences of five experimental parameters upon the mean size, yield and dispersity product were investigated via uniform design. These molar ratio NH3·H2O ZrOCl2, C2H5OH percentage reacting washing solutions, ZrOCl2 concentration, temperature surfactant PEG-800 dosage. condition experiments demonstrated that played a significant role improving absence higher percentage, better dispersity. By using dissolve ZrOCl2·8H2O conc. respectively mixing them, we carried out medium generate hydroxide precursor, which filtrated, washed with C2H5OH, dried calcined form well-dispersed zirconia.
