A studies on three-component systems of metal oxides, aimed among others at searching for
new phases formed in such systems, establishing conditions for their synthesis and determining
properties have gained crucial importance for designing of novel catalysts which can find
application in processes of oxidation of hydrocarbons. Study of the V 2 O 5 -NiO-In 2 O 3 system by
XRD, DTA and SEM methods has proved that a hitherto unknown compound Ni 2 InVO 6 occurs in
the system.
Obtained results have allowed us to divide investigated system V 2 O 5 -NiO-In 2 O 3 into seven
subsidiary subsystems and to determine temperatures and components concentration range in which
Ni 2 InVO 6 remains at equilibrium in solid state with other phases formed in corresponding binary
systems.

This ternary Ni–Pb–Sb system has a widely used in industry. For the complete definition of the
properties of the ternary Ni–Pb–Sb system, were characterized by microstructural SEM–EDS and
optical microscopy analysis, Brinell hardness tests and electrical conductivity measurements of the
alloys. Based on obtained experimental results for alloys from two vertical sections, isolines of
hardness and electrical conductivity for ternary Ni–Pb–Sb system were calculated. By application
of CALPHAD method there were calculated the isothermal cross section at 25°C. The phases on
calculated cross sections were found to be in a good agreement with experimentally determined
phase compositions in analyzed microstructures.
