Reduction of TiO2, ZrO2, and HfO2 for Target Preparation
Using a small bomb type reaction vessel 50–100 milligrams of TiO2, ZrO2 or HfO2 can be reduced to its metallic form at a temperature of ~ 1000°C using magnesium as reducing agent. The metal obtained contains negligible amount of impurity and can be evaporated for preparing metallic targets. It, however, cannot be rolled to thin foils. The yield of this process ranges from 80 to 90%.
