Due to high corrosion resistance, zirconium products, such as these rods, have many uses in medical equipment and to handle other highly corrosive chemicals. Zirconium rods also act as raw materials for other zirconium products, like crucibles and reactors, and can be consumed in zirconium electrodes.

Hafnium is a transition metal in group 4, period 6, and the d-block of the periodic table. It has a melting point of 2233 degrees Celsius. The trends across the transition metals are due to electrons filling an inner d-subshell (here, within the 5th ring), shielding the outer electrons from the increasing nuclear charge.

Hafnium reacts in air to form a protective film that inhibits further corrosion. The metal is not readily attacked by acids but can be oxidized with halogens or it can be burnt in air.
Stock solutions of zirconium and hafnium were prepared by dissolving the necessary amounts of Zr (NO 3) 4 and Hf(NO 3) 4 in double distilled water. The concentration of Zr and Hf in the aqueous phase was determined spectrophotometrically (23) using a Shimatzu UV- 160A. Batch experiments
