Abstract The ferroelec. orthorhombic phase and a new nonpolar tetragonal phase of yellow Sr8[Al12O24](CrO4)2 single crystals were studied by polarized light microscopy, DSC, permittivity measurements, spontaneous birefringence, and spontaneous polarization. The high perfection of the title crystals relative to the green form was demonstrated. The symmetry and microtwinning of the crystals are discussed.
