Abstract:Nanometer ZrO2-8(mole fraction, %) Y2O3 powders with the average particle size of 10 nm were prepared by the EDTA sol-gel method. DTA/TG, XRD, BET and TEM were employed to characterize the powders . The operating conditions such as pH value, concentration of solution, and quantity of EDTA were investigated in order to understand their effects on the specific surface area of the powders.
Key words: complex sol-gel ZrO2 nanometer powder EDTA
