Overview. Vanadium (V) is widely distributed in nature.At least 135 different minerals of vanadium have been identified, but deposits containing more than 1 or 2% are rare. An important fact to take into account when handling and preparing samples is that vanadium is found generally in five types of compounds namely sulfides, oxides, sulfates, vanadates and silicates.
Zirconia is a well known polymorph that occurs in three forms monoclinic (M), cubic (C), and tetragonal (T). Pure zirconia is monoclinic at room temperature, and is stable up to 1170 176;C. Above this temperature it transforms into the tetragonal and then into the cubic phase at 2370 176;C.
