BaZn2Si2O7 and the solid solution series BaZn2−xCoxSi2O7 (0<x≤2) as high temperature seals for solid oxide fuel cells studied by high-temperature X-ray diffraction and dilatometry

•We examined the thermal expansion of solid solutions BaZn2−xCoxSi2O7 (0

For sealing of solid oxide fuel cells, glasses from which crystalline phases with high coefficient of thermal expansion (CTE) can be crystallized are required. In this paper, a new solid solution series BaZn2−xCoxSi2O7 (0
