Rapid solidification of $\mathrm{ZrO}_2$–$8$ mol $\%$ $\mathrm{Y}_2\mathrm{O}_3$ melt

This paper deals with the singularities of crystallization of a pool with a melt produced by local heating of $\mathrm{ZrO}_2$–$8$ mol $\%$ $\mathrm{Y}_2\mathrm{O}_3$ ceramic by concentrated laser radiation. The effect of the semitransparency of the oxide, of the thickness of the melt, and of the rate of its cooling on the behavior of crystallization and on the structure of solidified layer is analyzed. The obtained results are compared with the results of crystallization of the melt of pure $\mathrm{ZrO}_2$.
