Hafnium(IV) oxide is the inorganic compound with the formula HfO2. Also known as hafnia, this colorless solid is one of the most common and stable hafnium compounds. It is an electrical insulator with a bandgap of 5.3~5.7 eV. Hafnium dioxide is an intermediate in some processes that give hafnium metal.

Hafnium Oxide Sputtering Targets
Circular: Diameter <= 14 inch, Thickness >= 1 mm;
Block: Length <= 32 inch, Width <= 12 inch, Thickness >= 1 mm.
Bonding is recommended for these materials. Many materials have characteristics that are not amenable to sputtering, such as brittleness and low thermal conductivity. This material may require a special ramp up and ramp down procedures. This process may not be necessary for other materials. Targets that have low thermal conductivity are susceptible to thermal shock.
