Abstract
A commercially pure Ti(CP-Ti) and Ti-25wt％Pd alloy for dental applications were cast into a phosphate-bonded Al$_2$ $O_3$/ $SiO_2$ investment mold and the surface of the casting specimens were investigated by means of SEM/EDS, XRD and XPS. The addition of 25wt％Pd in CP-Ti showed a moderate mold reaction owing to the considerable lowering of melting point. XRD analysis of the investment after burn-out treatment revealed that it consisted essentially of $SiO_2$, Al$_2$ $O_3$, P$_2$O$\_$5/, Mg$_3$(P $O_4$)$_2$, AlP $O_4$, Mg$_2$ $SiO_4$, MgAl$_2$ $O_4$ The mold reaction products were Ti$\_$5/Si$_3$ and Ti $O_2$ in case of CP-Ti casting and Ti $O_2$ and SiO$\_$x/ in case of Ti-25wt％ Pd casting.
