Abstract

The phase formation in the BaB2O4-NaF cut has been investigated by the methods of solid-phase synthesis, visual polythermal analysis, and spontaneous crystallization on a platinum loop. A range of primary crystallization of the new compound Ba2Na3[B3O6]2F (hexagonal system, P63/m, a = 7.346(1) Å, c = 12.636(2) Å) is revealed in this cut, which is used to grow single crystals of low-temperature barium borate modification β-BaB2O4.
