Wetting of hafnium dioxide by pure metals

The wetting of hafnium dioxide ceramics by pure metals, such as copper, silver, gold, germanium, silicon, tin, iron, cobalt, nickel, palladium, platinum, aluminum, titanium, and zirconium, is studied. Evidence of HfO2–iron interaction is found: relatively good wetting and darkening of ceramics near the drop. It is also revealed that HfO2 keeps its stoichiometry when interacts with noble metals, platinum and palladium.
