ABSTRACT:
A refractory metal silicide sputtering target is made by reacting refractory metal and silicon to about 70 to 90% completion of the reaction, comminuting the material, and then vacuum hot pressing the comminuted material to a high density compact having a theoretical density greater than about 95 percent and forming the metal silicide.
