Structures, Phase Equilibria, and Properties of HfO2
Jan 1, 2019 · Hafnium dioxide (HfO 2) has long been known as a refractory material due to its high melting temperature (~ 2800°C) and low thermal conductivity (1.5 W/m K) [1], [2]. Refractories are thermally insulating materials known to withstand high temperatures without being degraded and are used for high-temperature applications to reduce heat losses [3].
