Wetting of Hafnium Dioxide by Pure Metals

Abstract

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 palla-dium.
