ChemInform Abstract: Alkaline—Alkaline Earth Fluoride Carbonate Crystals ABCO3F (A: K, Rb, Cs; B: Ca, Sr, Ba) as Nonlinear Optical Materials.

Abstract KSrCO 3 F, RbSrCO 3 F, KCaCO 3 F, RbCaCO 3 F, CsCaCO 3 F, and Cs 3 Ba 4 (CO 3 ) 3 F 5 are obtained by spontaneous crystallization from molten mixtures of BCO 3 (B: Ca, Sr, Ba) and A 2 CO 3 /BF 2 (A: K, Rb, Cs).
