Coupled crystallization has been observed in the Al 3 O 3 /10%‐ZrO 2 system by heating an amorphous precursor Al /Zr copolymerized alkoxide network structure. A finely divided two‐phase material results which stabilizes tetragonal ZrO 2 to 1700°C and exhibits an unprecedented microstructure. During crystallization, the grain growth of ZrO 2 is coupled to the γ→α phase transformation of Al 2 O 3 .
