Method & Evidence

AimTo investigate the formation of crystalline phases and solid solutions in clinopyroxene-based glass-ceramic systems and evaluate their suitability for functional applications, particularly in solid oxide fuel cell (SOFC) sealing.

MethodExperimental material synthesis and characterization

ProcedureVarious glasses and glass-ceramics were prepared along the Enstatite-Diopside and Diopside-Ca-Tschermak joins. These were produced via melt-quenching for glasses, and sintering/crystallization of frits or monolithic glasses for glass-ceramics. The resulting materials were characterized using a range of analytical techniques.
