have anisotropic properties, originating in their crystallographic structure, thus it is important to study the properties of the single crystal form of these materials [1]. This will allow the enhancement of the properties that are significant in environmental barrier applications: thermal insulation, chemical resistance, as well as hardness and the compactness through the thermal expansion coefficient. It is well known that the rare earth silicates are a good candidate for such applications that require high temperature, however through studies of their single crystals we can improve the properties and extend their applicability [2]
