摘要	Environmental barrier coatings (EBCs) with thermomechanical robustness against calcium-magnesium-aluminum-silicate (CMAS) deposits are in high demand. The aim of this work was to clarify the influence of Sc3+ on the crystallization behavior of Yb-based coatings against CMAS deposits. The reaction products of solid solutions with compositions traversing the Sc2O3-Yb2O3 system indicate that Sc3+ tends to form [BO6] coordination polyhedra in the crystal structure to promote the formation of garnet and diopside, while Yb3+ occupies 7-, 8-, and 9-coordinate sites to crystallize apatite and silicocarnotite. The transformation of crystalline products from apatite/silicocarnotite to garnet/diopside greatly improves the efficiency of CMAS melt consumption and facilitates the prevention of its further penetration and corrosion. Based on the commonality of cation occupancy in crystallography, an A(CaO+YbO1.5)-B(ScO1.5+MgO+AlO1.5)-T(SiO2) pseudoternary phase diagram is established, which has great potential for describing phase equilibrium in coating-deposit systems and can provide guidance for the compositional design of corrosion-resistant coatings.
