A part made of composite material includes fiber reinforcement including silicon carbide fibers presenting an oxygen content less than or equal to 1 % in atomic percentage; and a matrix present in the pores of the fiber reinforcement and including at least one sintered silicate phase including at least one rare earth silicate, mullite, or a mixture of mullite and of at least one rare earth silicate, the matrix including at least a first phase including mullite and a second phase, different from the first phase, including at least one rare earth silicate.

A ceramic absorber for damping, in particular absorbing, vibrations, in particular combustion vibrations, preferably in gas turbines, which has a foam structure. For the ceramic absorber, the sound absorption capacity is set in a defined way and the efficiency is improved. The foam structure is based on a ceramic powder which contains either a component from the class of silicates or a component from the class of oxides, or a combination of a component from the class of silicates and a component from the class of oxides, and the foam structure has a homogeneous pore distribution.

The disclosure describes articles having coating systems configured to inhibit or prevent crystallization of TGO at the operating temperature of the article. An article includes a substrate defining a surface; a bond coat on the surface of the substrate; a coating layer that includes a boron dopant configured to inhibit crystallization of amorphous silicon dioxide thermally grown oxide on the bond coat at an operating temperature of the article. By inhibiting or preventing TGO crystallization, the described coating systems may increase a useable life of the component.
