Preparation of Niobium Metal Powder by Two-Stage …

Calcium has high reactivity for the reduction of niobium oxide to niobium. However, magnesium has an advantage over calcium that it has a high vapor pressure (0.078 bar) even at moderate temperature of 1123 K. Due to this, adequate control over the reaction conditions is possible for the reduction of niobium oxide with magnesium vapor.
