Oxide Dysprosium, est materia prima rudis pro Dysprosio Metalli, quod late in magnetibus Neodymo-Iron-boron adhibetur, speciales etiam usus in ceramicis, vitro, phosphoro, lasere et dysprosio metallo halide lampadis.
Alta puritas Oxidei Dysprosii in electronicis industria adhibetur, sicut antireflection efficiens in machinis photoelectricis.
Propter dysprosium altam effusio-neutroni absorptionem sectionis crucis, Dysprosium-Oxide-Nickel cermetus adhibentur in neutron-absorbens virgas potestate reactoria nuclei.
Dysprosium et eius compositiones valde obnoxiae magnetizationis, adhibentur in variis applicationibus notitia repono, sicut in disco duro.
