Thierry Hours, Pierre Bergez, J. P. F. Charpin, A. Larbot, C. Guizard, L. Cot

Abstract

This paper reports that submicron yttrium oxide was prepared from hydroxide precursors through a precipitation method. A parametric study was conducted at every stage from the yttrium hydroxide sols and powders, and also calcined oxide powders, were characterized with various techniques: light scattering, X-ray diffraction, infrared spectroscopy, specific area and particle size measurements, thermal analysis, and scanning electron microscopy.
