Besides a typical hexagonal pattern, several weak diffraction lines are discernible in the X-ray powder photograph of a synthesized indialite. It seems that the weak lines are caused from the presence of super-lattice or crystal-distortion in the indialite lattice, and therefore, the crystal is not necessarily hexagonal in the strict sense of the word. Thus the optically biaxial character of the indialite corresponds with the appearance of the weak diffraction lines.
