Conclusions
Chemical reaction between Sc2O3 and Ta, Mo, and W is not observed when they are heated to 2100°C in a protective medium for 4 h. The depth of diffusion of the metal into the oxide is less than the resolving power of the microscope (1μ). It is, therefore, theoretically possible to use scandium oxide as a dispersion-strengthening phase for metal artifacts of Ta, Mo, and W, for coating these artifacts with Sc2O3, etc.
