Abstract (en)

[origin: WO2012129431A1] A bond layer may include a composition that may be stable at temperatures above about 1410° C. An article may include a substrate, a bond layer formed on the substrate, and an overlayer formed over the bond layer. In some examples, the bond layer may include a substantially homogeneous mixture of Si and at least one of SiO2, Al2O3, ZrO2, a rare earth oxide, ZrSiO4, TiO2, Ta2O5, B2O3, an alkali metal oxide, or an alkali earth metal oxide. In other examples, the bond layer may include Si, an alkali metal oxide, and at least one of SiO2, Al2O3, ZrO2, HfO2, a rare earth oxide, ZrSiO4, HfSiO4, TiO2, Ta2O5, B2O3, or an alkali earth metal oxide. In other examples, the bond layer may include B2O3.
