Sažetak
The aim of this study was to investigate the chemical stability of monolithic yttria partially stabilized zirconia (Y-TZP) dental ceramics. Chemical stability was monitored by determining the amount of Al3+, Na+, Ca2+, K+, Si4+, Fe3+, Zn2+, Mg2+, Sr2+, Ba2+, Y3+ and Zr4+ ions released after 16 h immersion of Y- TZP dental ceramics in the 4 wt. % acetic acid solution at 80 °C, according to ISO Standard 6872 method. Mass concentration of eluted ions were determined by means of inductively coupled plasma mass spectrometry (ICP-MS). In the order to determinate corrosion rate, corrosion experiments were extended up to 32 days (768 hours) in following interval 16, 192, 384 and 768 hours. Obtained results indicated that dissolution of Y-TZP dental ceramics is negligible. Experimental results followed parabolic equation with the rate constant of 5.3×10-5 g2cm-4h-1.
