Abstract

Yttria-stabilized zirconia (YSZ) nanoparticles were synthesized through a sol-gel method using sucrose and pectin as organic precursors. These precursors are abundant in nature and cost effective. Different molar ratio of organic to inorganic (S:Zr4+) precursors were used. To determine the formed phase, x-ray diffraction (XRD) and Raman spectroscopy were performed. XRD pattern showed cubic phase for all S:Zr4+ ratios. However, Raman spectroscopy confirmed the cubic phase for samples with higher ratios. Crystallite size of two samples with molar ratio of 1:4 and 1:2 was calculated 17 nm using Scherrer equation. Thermal analysis and IR spectroscopy were applied to determine the reaction pathway.

 

Key words: Yttria-stabilized zirconia (8YSZ), sol-gel, Raman spectroscopy, cubic phase.
