| Abstract: | Coupled crystallization has been observed in the Al3O3/10%-ZrO2 system by heating an amorphous precursor Al /Zr copolymerized alkoxide network structure. A finely divided two-phase material results which stabilizes tetragonal ZrO2 to 1700°C and exhibits an unprecedented microstructure. During crystallization, the grain growth of ZrO2 is coupled to the γ→α phase transformation of Al2O3. |
