Abstract

An investigation has been carried out to develop investment shell moulds from ?- cristobalite and ?- cristobalite as filler materials in the investment slurry. The shell characteristics in terms of hot bending strength and thermal shock were measured. The cracks were observed in the investment shell moulds prepared from the slurry containing ?- cristobalite due to transformation of ?- to ?- cristobalite at 250oC. Silicon was detected within the titanium substrate owing to the violent reaction between cristobalite and molten titanium.
