Beschrijving
Hafnium(IV) oxide is used in optical coatings and in advanced metal-oxide-semiconductor devices. It is used as a gate insulator in field-effect transistors due to its high dielectric constant. It plays an important role as a possible candidate for resistive-switching memories, as a refractory material in the insulation of devices such as thermocouples and as a high-κ dielectric in DRAM capacitors. It is also used in the preparation of hafnium tetrachloride.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
