UNSPECIFIED (1994) PREPARATION AND CHARACTERIZATION OF LN(2)ZR(2)O(7) MICROSPHERES BY AN INORGANIC SOL-GEL ROUTE. JOURNAL OF MATERIALS SCIENCE, 29 (23). pp. 6076-6078. ISSN 0022-2461Full text not available from this repository.
Free-flowing Ln(2)Zr(2)O(7) microspheres (Ln = lanthanide) were prepared by an aqueous inorganic set-gel route without any intermediate phase formation. The gel spheres obtained at room temperature were shown by X-ray diffraction to be amorphous but calcination to 750 degrees C produced fully crystalline fluorite phases. On calcination to 850 degrees C, pyrochlore phases were formed with suitable lanthanides. The microspheres were characterized by X-ray diffraction and scanning electron microscopy with energy dispersive analysis of X-rays to give accurate determination of structure, composition and crystallite size.
