摘要：
The purpose of this study is to obtain nanometric zirconia powders, by sol-gel method, using precursors of different chemical nature - inorganic (ZrCl4) and organic (C12H28O4Zr). The obtained gels were dried at 100 degrees C, and then heat treated to 1000 degrees C for 2 hours. In order to identify obtained phases and their degree of crystallinity, powders were analyzed using X-ray diffraction. Analyses of scanning electron microscopy and transmission electron microscopy have been used to investigate the morphology and size of the obtained powders. Experimental analyzes show that, from different precursors (organic and inorganic), nanometric powders of partially stabilized zirconia with CaO are obtained.
