Reactive sintering of ceramics on the base of boron nitride was studied, and the inertfiller was given in this paper.

Although GF is electrically inert, its presence can increase the effective concentration of the conductive filler by holding up some space, therefore the conductivity of the material increases.
Because TIG welded joints without filler wire always hold low strength and poor formation, tungsten inert gas welding process with filler wire is inevitable.
