Orientations and seed type effect on Al2O3-YAG-ZrO2 eutectic microstructure solidified from the melt by the micro-pulling down technique

Cr-doped Al2O3–YAG binary and Al2O3–YAG–ZrO2 ternary eutectic materials crystallized by the micro pulling down technique and their characterization

“…The eutectic ceramic materials offer technical characteristics in the quality of hard material and not only scratch resistance, biocompatibility, insensitivity to any chemical attack, resistance to friction and abrasion but also aesthetic advantages intended for dressing applications. [5][6][7] The Al 2 O 3 -YAG binary and Al 2 O 3 -YAG-ZrO 2 ternary systems [8][9][10][11] are among the eutectic ceramic materials that are identified to be the most important composite materials due to directional and rapid solidification from the melt. 12,13 The high melting temperature >1500 °C allows them to work stably in an oxidizing environment due to inherent chemical-physical properties.…”
