Hafnium (IV) dioxide nanoparticles

Hafnium dioxide, also known as hafnia, is an electrical insulator with a band gap of 5.3-5.7 eV.

It’s also a refractory material due to its high melting temperature (~ 2800°C) and low thermal conductivity (1.5 W/m K).

We at Particular Materials synthesize nano HfO2 and we produce and supply dispersions with excellent stability, monodispersity and fully disaggregated state.

Technical Information

In order to be able to take advantage of the various properties of hafnium dioxide nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.

Related Applications and Industries

Key applications of hafnium dioxide nanoparticles are as follows:

  • Coatings: the optical and thermal properties of hafnia make hafnium oxide nanoparticles of particular use in various coatings, including applications such as optical coatings and as a component in composite films for insulation
  • Synthesis of various related compounds and structures
  • Insulation: the high melting point of hafnium oxide makes it of particular use as a refractory insulator for high-temperature devices
  • Electronics: used in various metal-oxide semiconductors, transistors, and other electronic devices and materials
  • Catalysts, additives, dopants
