An article comprises a body having a coating. The coating comprising a eutectic system having a super-lattice of a first fluoride and a second fluoride. The coating includes a glaze on a surface of the coating, the glaze comprising the eutectic system having the super-lattice of the first fluoride and the second fluoride.

Ceramics and glass-ceramics have low and/or negative coefficients of thermal expansion. Crystalline phases of the formula AM.sub.2Si.sub.2-yGe.sub.yO.sub.7 (A=Sr and Ba and M=Zn, Mg, Ni, Co, Fe, Cu, Mn, with Sr, Ba and Zn necessarily having to be present) can be produced by conventional ceramic processes or by crystallization from glasses. The compositions form solid solutions, where the elements indicated as component M can be replaced by one another in virtually any concentration but the concentration of Zn must always be at least 50% of the sum of all components indicated under M. The stoichiometry of these silicates and also their structure can differ to a greater or lesser extent.

A method of fabricating a ceramic component includes hot pressing a composite component with a glass powder/filler cover mixture to form a consolidated glass-based coating on the composite component.
