    摘要: An article comprising a substrate containing silicon and at least one layer which contains a coefficient of thermal expansion (CTE) tailoring additive in an amount sufficient to maintain a compatible CTE with at least one adjacent layer and the substrate. In one embodiment there is provided an article comprising a silicon containing substrate and at least one layer comprising a niobate selected from the group comprising niobates of the formula a(alkaline earth metal oxide)•b(NbO x ) where x = 1 to 3 and b = 1/3a to 3a, NbO x in an amount of 1 to 75 wt.% to an oxide selected from the group consisting of MgO, CaO, SrO, BaO, Al 2 O 3 , Y 2 O 3 , L 2 O 3 , rare earth oxides and mixtures thereof where x = 1 to 3 (for example NbO, NbO 2 , Nb 2 O 3 , Nb 2 O 5 ), particularly Nb 2 O 5 •Al 2 O, and 2BaO•2SrO•3Nb 2 O 5 .
