NN1578 Nano Hafnium Oxide Powder (CAS No. 12055-23-1)

Nano Hafnium Oxide Powder Description

Nano Hafnium Oxide Powder is an intermediate in some processes that give hafnium metal. Hafnia is used in optical coatings and as a high-κ dielectric in DRAM capacitors and in advanced metal-oxide-semiconductor devices. Because of its very high melting point, hafnia is also used as a refractory material in the insulation of such devices as thermocouples, where it can operate at temperatures up to 2500℃. Multilayered films of hafnium dioxide, silica, and other materials have been developed for use in the passive cooling of buildings.
