| Summary: | In this work, effects of ZrO 2 additive concentration (0-65 wt%) on leucite crystallization and microstructural evolution of dental porcelain ceramics derived from a twostep sintering technique were examined by using a combination of X-ray diffraction, Scanning electron microscopy and Energy dispersive X-ray techniques. The amount of ZrO 2 additives has been found to be one of the key factors controlling leucite formation and microstructure on the zirconia surface in dental porcelain ceramics. It is likely that the ZrO 2 additives of ≤ 10 wt% act as nucleating agent for the leucite crystallization leading to larger amount and size of leucite particles. Statistical differences (p < 0. 05) of leucite particle sizes were found only between the ZrO 2 modified and the unmodified porcelains. |
