Dysprosium oxide, eyaziwa ngokubaDy2O3, yinxalenye yentsapho enqabileyo yomhlaba. Ngenxa yeempawu zayo ezizodwa, isetyenziswa ngokubanzi kumashishini ahlukeneyo, kodwa umbuzo osoloko uvela kukuba ingaba i-dysprosium oxide iyanyibilika emanzini. Kweli nqaku, siza kuphonononga ukunyibilika kwe-dysprosium oxide emanzini kunye nokubaluleka kwayo kwizicelo ezahlukeneyo.
Ukusombulula ingxaki yokuqala, i-dysprosium oxide inyibilika ngokuyinxenye emanzini. Xa ixutywe namanzi, iyasabela kwaye yenze ihydroxide. Ukusabela phakathi kwe-dysprosium oxide kunye namanzi ngolu hlobo lulandelayo:
Dy2O3 + 3H2O → 2Dy(OH)3
Ukusuka kwindlela esisabela ngayo sinokubona ukuba amanzi asebenza njenge-reactant, ukuguqulai-dysprosium oxidekwi-dysprosium hydroxide. Le nxalenye ye-solubility yenza i-dysprosium oxide isetyenziswe kwiintlobo ezahlukeneyo zezicelo ezifuna izisombululo ezisekelwe emanzini.
Nangona kunjalo, kubalulekile ukuqaphela ukuba i-dysprosium oxide ayinyibiliki ngokupheleleyo emanzini. I-solubility yayo ilinganiselwe kwaye ininzi ye-dysprosium oxide iya kuhlala ikwimo eqinileyo nasemva kokudibana ixesha elide namanzi. Oku kunyibilika okulinganiselweyo kwenza i-dysprosium oxide ilungele izicelo ezifuna ukukhutshwa okulawulwayo kweeyoni ze-dysprosium.
I-solubility ye-dysprosium oxide emanzini ineempembelelo ezibalulekileyo kumashishini ahlukeneyo. Esinye isicelo esiphawulekayo sikwintsimi ye-catalysis. I-Dysprosium oxide isetyenziswa ngokuqhelekileyo njenge-catalyst kwiindlela ezahlukeneyo zeekhemikhali. Ukunyibilika kwayo ngokuyinxenye emanzini kuyivumela ukuba idibane ne-reactants inyibilikiswe emanzini kwaye ikhuthaze ukusabela okufunwayo. I-dysprosium hydroxide eyenziweyo isebenza njengeentlobo ezisebenzayo ngexesha lenkqubo ye-catalytic, evumela ukusabela ukuba kuqhubeke ngokufanelekileyo.
Olunye usetyenziso olubalulekileyo lwe-dysprosium oxide kukuveliswa kwe-phosphors. Iiphosphors zizinto ezifunxa amandla kwaye zikhuphe ukukhanya. I-phosphors ye-Dysprosium-doped iqulethe i-dysprosium oxide njenge-dopant kwaye ineempawu ezizodwa zokukhanya. I-solubility encinci ye-dysprosium oxide emanzini iqinisekisa ukuba i-phosphor igcina iimpawu ezifunwayo nangona ibonakaliswe kumswakama okanye ukufuma.
Ukongezelela, i-solubility ye-dysprosium oxide emanzini nayo idlala indima ebalulekileyo kwimiba yendalo kunye nempilo. Ngenxa yokunyibilika kwayo okulinganiselweyo, i-dysprosium oxide ayinakwenzeka ukuba ingcolise amanzi okanye ibeke umngcipheko omkhulu kubomi basemanzini. Le propati yenza ukuba ibe yindawo efanelekileyo yezicelo apho ukhuseleko lokusingqongileyo luyinkxalabo.
Kufuphi,i-dysprosium oxide (Dy2O3)iyanyibilika ngokuyinxenye emanzini. Nangona inganyibiliki ngokupheleleyo, ukunyibilika kwayo kunika izicelo ezibalulekileyo kumashishini ahlukeneyo. Iphendula ngamanzi ukwenza i-dysprosium hydroxide, esetyenziswa kwi-catalysis kunye nemveliso yephosphor. Ukongezelela, ukunyibilika okulinganiselweyo kwe-dysprosium oxide kukwanegalelo ekuqwalaseleni ukhuseleko lokusingqongileyo. Ukuqonda i-solubility ye-dysprosium oxide emanzini kubalulekile ukuxhaphaza iimpawu zayo ezizodwa kunye nokwandisa amandla ayo kwiinkqubo ezahlukeneyo.
