N2 - Transparent crystals of K 2 Ba(NO 3 ) 4 were obtained from water solution. The phase diagram of the Ba(NO 3 ) 2 -KNO 3 -H 2 O system was constructed on the basis of experimental data, using X-ray phase analysis. For the first time the crystal structure of K 2 Ba(NO 3 ) 4 was determined as tetragonal (I-42m) with unit cell parameters a = b = 8,3126(7) Å, c = 7,7711(6) Å, V = 536,988 Å 3 . It was found that K 2 Ba(NO 3 ) 4 is irreversibly decomposed into KNO 3 and Ba(NO 3 ) 2 with decomposition temperature 197.3 °C. K 2 Ba(NO 3 ) 4 crystal is transparent in the range of 0.25–2.2 μm, where an absorption peak with the maximum at 0.3 μm is observed. The band gap is about 5 eV.
