Structural and compositional comparison of Si3N4 ceramics with different fracture modes

Two similarly processed yttrium oxide-doped Si3N4 ceramics containing differing amounts of amorphous phase are studied. Differences in the fracture mode of these two materials have been analysed structurally and compositionally by transmission electron microscopy. In agreement with the chemistry of...
