An analysis has been made of Cameron's data on the variation of the cell dimensions of mullite for compositions with additions of more than 1.0% of Fe + Ti for samples crystallizing out of the melt phase. It was observed that, depending on the amount of either iron oxide or titania added, the cell dimensions change with respect to changes in cell volume, exhibiting shrinkage along either the b or c cell edges. Increasing amounts of titania appear to influence the c cell edge in preference to the a and b edges. The overall cell symmetry, however, is preserved with a simultaneous increase in the a cell edge with change in the cell volume.
