Mechanical properties of tape casted Lanthanum Tungstate for membrane substrate application

Mechanical properties of BaCe0.65Zr0.2Y0.15O3- proton-conducting material determined using different nanoindentation methods

“…Elastic modulus, hardness and fracture toughness values are often derived via indentation testing [24][25][26]. However, for the determination of the elastic modulus, impulse excitation testing is suggested to be more representative of macroscopic long-range behavior, while deriving of the data from the geometry-specific resonance frequency [27] requires specimens with specific shape and dimensions.…”

Chemical and mechanical stability of BCZY-GDC membranes for hydrogen separation

“…Even if thermomechanical studies and lifetime predictions have been performed in deep for oxygenconducting ceramic membranes also in asymmetrical configuration [25][26][27], to the best of our knowledge, very few studies have been conducted onto planar ceramic membranes for hydrogen separation, being the latter focused only onto lanthanide tungstate-based systems [28][29][30][31].…”

Mechanical properties of BaCe0.65Zr0.2Y0.15O3- – Ce0.85Gd0.15O2- dual-phase proton-conducting material with emphasis on micro-pillar splitting

“…Elastic modulus and hardness can be determined using indentation testing [42][43][44], while the validity of conventional indentation testing-based fracture toughness investigations is still under discussion [45]. Recently, Sebastiani et al [46][47][48][49] developed fracture toughness assessment based on a micro-pillar indentation splitting test based on sharp indentations into micro-pillars prepared via focused ion beam (FIB) milling.…”
