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.
