Question

Which of the following type of zirconium is used in an atomic-energy application?

(a) Induction-melted zirconium

(b) Arc-melted zirconium

(c) Both arc-melted and induction-melted zirconium

(d) Neither arc-melted nor induction melted zirconium

This question was addressed to me by my college professor while I was bunking the class.

My doubt is from Prevention topic in chapter Corrosion Prevention of Corrosion Engineering

Answer 1

The correct answer is (b) Arc-melted zirconium

To explain I would say: Arc-melted zirconium is more corrosion resistant than induction-melted zirconium because of more impurities in the latter. Hence arc-melted zirconium is used in an atomic-energy application.
