Which of the following metals or alloys cannot be used for making crucibles? Correct Answer Mercury

For the making of crucibles, nickel and zirconium have been employed in the recent times. Platinum had been used for this purpose in the earlier times, owing to its inertness, but mercury cannot be used for making it.
