“…Then the very spectral position of the IP and the corresponding material para-meters depend notably on the growing conditions, stoichiometry and the impurities involved and, therefore, vary from sample to sample. For instance, even such basic parameter as the wave-coupling coefficient in wurtzites is heavily determined by the internal mechanical stresses in crystal samples [3,4,8,16]. To overcome this deficiency, it would be desirable to work with solutiongrown crystals revealing more stable and reproducible characteristics.…”

Abstract. In this work we have grown single crystals K x (NH 4 ) 2-x SO 4 (x  1.75), which belong to a potassium-ammonium sulfate family, and studied their roomtemperature structure. Spectral dependences of the principal refractive indices and principal optical birefringences are measured in the visible region. Anomalous birefringence dispersion is observed along the light propagation direction parallel to the principal x axis. According to our birefringence extrapolation based on the Sellmeier fit for the refractive indices, the symmetry of optical indicatrix at the room temperature should increase at the light wavelength λ IP  1350±60 nm. This corresponds to a specific 'isotropic point' defined by the condition n x (λ IP ) = n y (λ IP ), which has not been detected in either K 2 SO 4 or (NH 4 ) 2 SO 4 crystals.
