I-Dysprosium oxide, eyaziwa nangokuthiI-Dy2O3, iyinhlanganisela eyingxenye yomndeni wezakhi zomhlaba ezingavamile. Ngenxa yezakhiwo zayo eziyingqayizivele, isetshenziswa kabanzi ezimbonini ezihlukahlukene, kodwa umbuzo ovame ukuvela ukuthi i-dysprosium oxide iyancibilika emanzini. Kulesi sihloko, sizohlola ukunyibilika kwe-dysprosium oxide emanzini kanye nokubaluleka kwayo ezinhlelweni ezahlukene.
Ukuxazulula inkinga yokuqala, i-dysprosium oxide inyibilika kancane emanzini. Uma ixutshwe namanzi, iyasabela futhi yakhe i-hydroxide. Ukusabela phakathi kwe-dysprosium oxide namanzi imi kanje:
I-Dy2O3 + 3H2O → 2Dy(OH)3
Kusukela ekuphenduleni singabona ukuthi amanzi asebenza njenge-reactant, convertingi-dysprosium oxideku-dysprosium hydroxide. Lokhu kuncibilika kwengxenye kwenza i-dysprosium oxide isetshenziswe ezinhlelweni ezihlukahlukene ezidinga izixazululo ezisekelwe emanzini.
Nokho, kubalulekile ukuqaphela ukuthi i-dysprosium oxide ayincibiliki ngokuphelele emanzini. I-solubility yayo ilinganiselwe futhi iningi le-dysprosium oxide lizohlala lisesimweni esiqinile ngisho nangemva kokuxhumana isikhathi eside namanzi. Lokhu kunyibilika okulinganiselwe kwenza i-dysprosium oxide ilungele izinhlelo zokusebenza ezidinga ukukhululwa okulawulwayo kwama-ion e-dysprosium.
Ukuncibilika kwe-dysprosium oxide emanzini kunemithelela ebalulekile ezimbonini ezahlukene. Isicelo esisodwa esiphawulekayo sisemkhakheni we-catalysis. I-Dysprosium oxide ivame ukusetshenziswa njenge-catalyst ekuphenduleni kwamakhemikhali okuhlukahlukene. Ukuncibilika kwayo ingxenye emanzini kuyivumela ukuthi ihlanganyele nezinto ezisabelayo ezincibilike emanzini futhi ikhuthaze ukusabela okufunayo. I-dysprosium hydroxide eyakhiwe isebenza njengezinhlobo ezisebenzayo phakathi nenqubo ye-catalytic, evumela ukusabela ukuthi kuqhubeke kahle.
Okunye ukusetshenziswa okubalulekile kwe-dysprosium oxide ukukhiqizwa kwe-phosphors. I-Phosphors yizinto ezithatha amandla futhi zikhiphe ukukhanya. Amaphosphor e-Dysprosium-doped aqukethe i-dysprosium oxide njenge-dopant futhi anezici ezihlukile zokubona. I-solubility elinganiselwe ye-dysprosium oxide emanzini iqinisekisa ukuthi i-phosphor igcina izakhiwo zayo ezifunwayo ngisho nalapho ivezwe kumswakama noma umswakama.
Ngaphezu kwalokho, i-solubility ye-dysprosium oxide emanzini nayo idlala indima ebalulekile ezicini zemvelo nempilo. Uma kubhekwa ukunyibilika kwayo okulinganiselwe, i-dysprosium oxide ayinakwenzeka ukuthi ingcolise amanzi noma ibe yingozi enkulu empilweni yasemanzini. Lesi sakhiwo sikwenza kube indawo ekahle yezicelo lapho ukuphepha kwemvelo kuyinkinga.
Kafushane,i-dysprosium oxide (Dy2O3)iyancibilika kancane emanzini. Nakuba ingancibiliki ngokuphelele, ukuncibilika kwayo kuyinikeza izinhlelo zokusebenza ezibalulekile ezimbonini ezihlukahlukene. Iphendula ngamanzi kwenze i-dysprosium hydroxide, esetshenziswa ku-catalysis nokukhiqizwa kwe-phosphor. Ngaphezu kwalokho, ukuncibilika okulinganiselwe kwe-dysprosium oxide nakho kunomthelela ekucatshangelweni kokuphepha kwemvelo. Ukuqonda ukuncibilika kwe-dysprosium oxide emanzini kubalulekile ukuze kusetshenziswe izakhiwo zayo eziyingqayizivele futhi kwandiswe amandla ayo ezinhlelweni ezihlukahlukene.
