This paper presents the results of a combined
experimental and theoretical study of microstructure and
thermal shock resistance of an aluminosilicate ceramic.
Shock-induced crack growth is studied in sintered structures
produced from powders with different particle size
ranges. The underlying crack/microstructure interactions
and toughening mechanisms are elucidated via scanning
electron microscopy (SEM). The resulting crack-tip shielding
levels (due to viscoelastic crack bridging) are estimated
using fracture mechanics concepts. The implications of the
work are discussed for the design of high refractory
ceramics against thermal shock.
