Abstract
Mullite has be identified as a potential material for manufacturing gas turbine engine parts due to its properties like high temperature strength, good thermal shock resistance and low thermal coefficient of expansion. In the present study, the potential of using powder injection molding to fabricate parts from mullite was investigated. The properties of the developed feedstock were used to simulate and identify suitable molding conditions for fabricating parts like miniature turbine stators. A test part was successfully injection molded from the developed feedstock. The results from the study confirm the ability of powder injection molding to fabricate complex shapes made from mullite.
