Sažetak
This study, tchemical stability of Y-TZP dental ceramic was determined by the modified standard method ISO 6872. The phase composition of Y-TZP dental ceramic was determined by X-ray diffraction (XRD) analysis, the microstructure was analyzed by Scanning Electron Microscopy (SEM). Chemical stability of investigated Y-TZP dental ceramic was determined by measuring eluted Al3+, Na+, Ca2+, K+, Si4+, Fe3+, Zn2+, Mg2+, Sr2+, Ba2+, Y3+ and Zr4+ions by High Resolution Inductively Coupled Plasma Mass Spectrometry (HR-ICP-MS). According to the standard ISO 6872 chemical stability of dental ceramic is carried out in 4 wt. % CH3COOH aqueous solution at 80 °C during16 h. In this work, exposure time was extended up to 768 hours (32 days) in order to determine the corrosion rate constant. The parabolic reaction rate constant was 5.3 × 10-5 g2 cm-4 h-1. XRD analysis showed that the corrosion process course of partial tetragonal to monoclinic phase transformation of ZrO2.
