Crystal structure of mullite
Komensky University, Bratislava
Abstract: It was detd. by Fourier analysis that the model of crystal structure of mullite, given by Taylor (CA 23, 2126), was basically correct. Single crystals of electrofused mullite contg. SiO2 22.19, Al2O3 76.85, Fe2O3 0.56, and TiO2 0.44% were tested. The position of OIII is statistically occupied. By a direct structure analysis, the existence of sillimanite double chain tetrahedra SiO44- was proven. The formula for mullite should be in the form: Al[Si2-xAlxO11/2-x/2, where x is 1.25-1.40 for 3/2 to 2/1 mullite.
