Characteristics of Nanocrystalline Zirconia Powder in the ZrO2- Y2O3-CeO2-Al2O3 system with 0.1wt. СоО

摘要

Matrix (mol%) 95ZrO2-3Y2O3-2CeO2 was produced by hydrothermal synthesis from a mixture of previously precipitated hydroxides. -Al2O3 and Co(NO3)3 were added by mechanical mixing. The properties of nanocrystalline powders with a complex chemical composition (wt.) [90 (ZrO2-CeO2-Y2O3)-10Al2O3]-(0,1Al2O3-0,1CoO) after heat treatment in the temperature range from 400 to 1300 °C were investigated by XRD phase analysis and BET measurements. During heat treatment powders retained in nanocrystallite state (primary particle size of the zirconia solid solution varies from 14 to 83 nm), and its specific surface area decreases from 99,7 m2/g to 1.51 m2/g.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35263
