…gaseous hydrogen fluoride (HF), yielding thorium tetrafluoride (ThF₄). The metal is obtained by the Spedding process, in which powdered ThF₄ is mixed with finely divided calcium (Ca) and a zinc halide (either zinc chloride or zinc fluoride) and placed in a sealed, refractory-lined “bomb.” Upon heating to approximately 650 °C…
