Kinetics of Lanthanum and Yttrium Doped Zirconia Crystallization by X-ray Powder Diffraction

Abstract

The need to develop high performance materials is increasing nowadays. Due to its extraordinary range of properties, the yttria-doped zirconia is placed in a special place among the ceramic oxide systems. Co-doping with other rare earths oxides, such as Lantania is required in order to obtain better properties for some applications. The aim of the following paper is to determine the kinetic growth parameters of the crystallite according to the nature and the content of dopant used. The ZrO2 - 3Y203 - nLa203 (n = 3, 6, 9) samples were obtained through a hydrothermal process.
