| dc.description.abstract | The Effect of quartz and mullite crystalline phases on the strength of triaxial porcelain in the
system quartz-feldspar-kaolin composed of20% wt silica and feldspar/kaolin ratio of 5:8 have been
investigated. It was found that secondary mullite crystals enhanced both the compressive strength
and elastic properties of porcelain while excess glass formation decreased the fracture strength of
porcelain as a result of the combined effect of circumferential cracks around quartz grains and the
microcracks within the quartz grains. The former was due to the difference in the thermal
expansion coefficient between the glassy and the quartz phases while the latter was due to a- to ~b
quartz phase inversions. | en |
