Physicochemical study of the Sb2Se3-Ho2Se3 system
The chemical interaction in the Sb 2 Se 3 -Ho 2 Se 3 system was studied by physicochemical analysis methods (by differential thermal, X-ray powder diffraction, and microstructural analyses and also by density and microhardness measurements). The state diagram of the system was constructed. It was fo...
