Little work has been done to relate the known wetting behaviors to the sintering and grain growth in alumina doped with copper, copper-titanium, and titanium. A systematic study has connected the wetting of copper, titanium, and copper-titanium alloys on polycrystal alumina to grain growth when sintered in atmospheres varying from highly reducing to ambient. The results from a preliminary study on these systems along with established wetting behavior were used as a starting point for the parameters selected. The varying degrees of wettability along with the influence of different atmospheres were compared side by side. The results take us one step further in understanding how grain growth is controlled and influenced by complexions.
