Title:
NANOSCALE YTTRIUM-ZIRCONIUM COMPOUND OXIDE OBTAINED BY THERMAL DECOMPOSITION, METHOD OF PRODUCING THE SAME, AND METHOD OF USING OF THE SAME
Document Type and Number:
Japanese Patent JP3961365
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce a nanoscale yttrium-zirconium compound oxide by thermal decomposition which is characterized in the that the intrinsic tetragonal crystal system is maintained without transformation to the monoclinic system even after being stored for one month.
SOLUTION: The nanoscale yttrium-zirconium compound oxide is produced by spraying an yttrium compound and a zirconium compound or a solution or a suspension obtained by dissolving or dispersing these compounds in a solvent, and then converting these compound into the yttrium-zirconium compound oxide at a temperature higher than 200°C in a flame, preferably an detonating gas.
