KirstenMixed crystals V|_^NbA0 2 exist about the whole area of quasibinary line V 0 2-N b02. The phase relations between these compositions V 0 2-N b 02 and the binary and ternary phases of the described subsystems were cleared using chemical transport reactions (CTR) and solid state reactions. A more precise phase diagram of the ternary system V/Nb/O is given for the temperature range of 900 -1000°C.
