Free surfaces of 2:1 mullite (2Al2O3·SiO2) specimens decomposed with the evolution of SiO and O2 when they were heated at high temperatures under low partial pressures of O2; this reaction was analyzed thermodynamically. In addition, bubbles were observed at internal interfaces between mullite and fused‐SiO2 diffusion couples. These bubbles, when formed at 1 atm ambient pressure between 1650° and 1800°C, resulted from reaction of Si particles and residual SiO2‐rich glass in the fused cast mullite.
