Abstract
Thermal analyses of and in closed titanium metal crucibles were made in the range from . The melting point of was confirmed to be 1025°C. The phase diagram of the system has two compounds and one eutectic. The eutectic point lies at and 605°C. One compound, , is formed by a peritectic reaction at 628°C; the other one, , decomposes in the solid state at 548°C.The free energy curves derived from the phase diagram indicate that liquid melts have the highest stability at temperatures up to about 800°C at the composition , thus making probable the existence of complex ions. At higher temperatures or in the presence of large cations, more complex ionic clusters are likely to exist.
