With the increase of x, the content of [Formula: see text] gradually increased, the Al 2 SiO 5 phase disappeared, and the SnO 2 and MgAl 2 O 4 phases appeared. In addition, the cell volume of the ceramic changes with the increase of x, which indicates that partial [Formula: see text] successfully enters the lattice with ion substitution and lattice distortion. The relative density and [Formula: see text] are highly correlated. The quality factor (Qf) is not only affected by the relative density but also by the symmetry of the [Si 4 Al 2 ] ring. The bond strength as an evaluation of the stability of the crystal structure determines the magnitude of [Formula: see text].
