Provided herein are barrier compositions, articles comprising barrier compositions, and methods for forming a barrier. By some approaches, a barrier composition comprises a ceramic material including a stabilized zirconia and a binder. The ceramic material includes a stabilized zirconia (ZrO2) having a coefficient of thermal expansion (CTE) in the range of about 10×10−6/° C. to about 12×10−6/° C., the ceramic material present in the barrier composition in an amount in the range of about 10 percent by weight and about 75 percent by weight. The binder includes a phosphate-based compound, the binder present in the barrier composition in an amount in the range of about 40 percent by weight to about 75 percent by weight.
A barrier composition for a glass-metallic interface layer for forming a barrier layer between a glass seal and an adjacent metallic component, the barrier composition comprising:
An electrochemical cell comprising:
A method of making an electrochemical cell, the electrochemical cell comprising an anode, a cathode and an electrolyte disposed therebetween and a metallic interconnect disposed adjacent to at least one of the anode or the cathode, the method comprising forming a barrier layer comprising a ceramic powder on the metallic interconnect, the ceramic powder comprising a ceramic material having a coefficient of thermal expansion (CTE) in the range of about 10×10−6/° C. and about 12×10−6/° C. and a binder comprising a phosphate-based compound.
