High gadolinium
Web5 de jan. de 2024 · Other uses of gadolinium include the manufacture of certain iron and chromium alloys, computer chips and CDs, microwave ovens, and televisions. The pure metal is fairly stable in air but tarnishes in moist air. It slowly reacts in water and dissolves in dilute acid. At high temperatures, gadolinium reacts with oxygen.
