N2 - The phase relations in the NaB3O5-KB 3O5 pseudobinary system are investigated using high-temperature X-ray powder diffraction, differential scanning calorimetry, and the annealing and quenching techniques. Solid solutions Na 1-xKxB3O5 (0.5 < x ≤ 1.0) based on the KB3O5 phase are found in the system at temperatures below 650-670°C. The replacement of potassium atoms by sodium atoms is accompanied by the contraction of the structure along the a and c axes. The parameter b (the direction of channels in the structure) is insensitive to the substitution of sodium atoms for potassium atoms. No isomorphic miscibility on the basis of NaB3O5 is revealed in the system. In the region from 0 to 50 mol % KB3O5, there exist two phases, namely, Na1-xKxB3O5 (x≈0.5) and β-NaB3O5.
