Hafnium Oxide HfO2 Pellets Tablets Evaporation Materials. Thermal Evaporation of Hafnium Oxide (HfO 2). Hafnium oxide can be thermally evaporated from a tungsten boat such as our EVS8B005W, if using a KJLC ® system. We estimate a deposition rate of 5 angstroms per second when the evaporation temperature is at ~2,500°C.
