Na 1886, onye France Boise Baudelaire nke ọma kewapụrụ holmium n'ime ihe abụọ, nke a ka maara dị ka holmium, na nke ọzọ a na-akpọ dysrosium dabere na nkọwa nke "ihe siri ike inweta" site na holmium (Figure 4-11).Dysprosium na-arụ ọrụ dị mkpa ugbu a n'ọtụtụ mpaghara teknụzụ dị elu. Isi ojiji nke dysprosium bụ ndị a.
(1) Dị ka ihe mgbakwunye maka neodymium iron boron magnets na-adịgide adịgide, ịgbakwụnye 2% ruo 3% dysprosium nwere ike imeziwanye mmanye ya. N'oge gara aga, ọchịchọ maka dysprosium adịghị elu, ma na-arịwanye elu nke neodymium iron boron magnet, ọ ghọrọ ihe mgbakwunye dị mkpa, nke nwere ọkwa 95% ruo 99.9%, na ọchịchọ na-arịwanye elu ngwa ngwa.
(2) Dysprosium na-eji dị ka ihe activator maka phosphor, na trivalent Dysprosium bụ a na-ekwe nkwa ịgbalite ion maka otu emission center tricolor luminescent ihe. Ihe mejupụtara ya bụ ụgbụgbọ ikuku abụọ, otu bụ ikuku na-acha odo odo, nke ọzọ bụ ikuku na-acha anụnụ anụnụ. Dysprosium doped luminescent ihe nwere ike iji dị ka tricolor phosphor.
(3) Dysprosium bụ ihe dị mkpa ígwè akụrụngwa maka nkwadebe nke nnukwu magnetostrictive alloy Terfenol, nke nwere ike ime ka kpọmkwem n'ibu mmegharị na-enweta.
(4) Enwere ike iji metal dysprosium mee ihe dị ka ihe nchekwa magneto-optical nwere nnukwu ndekọ ọsọ na ọgụgụ isi.
(5) Maka nkwadebe nke oriọna dysprosium, ihe na-arụ ọrụ na-arụ ọrụ na oriọna dysprosium bụ dysprosium iodide. Ụdị oriọna a nwere uru dị ka nchapụta dị elu, ezigbo agba, oke agba agba, obere nha, na arc kwụsiri ike. Ejirila ya dị ka isi iyi ọkụ maka ihe nkiri, mbipụta na ngwa ọkụ ndị ọzọ.
(6) A na-eji Dysprosium tụọ ụdị neutron dị iche iche ma ọ bụ dị ka neutron absorber na ụlọ ọrụ ike atọm n'ihi nnukwu akụkụ nke neutron weghara akụkụ obe.
(7) DysAlsO12 nwekwara ike iji dị ka ihe ndọta na-arụ ọrụ maka refrigeration magnetik. Site na mmepe nke sayensị na teknụzụ, mpaghara ngwa nke dysprosium ga-aga n'ihu na-agbasa ma gbasaa.
