I-Nickel oxide Powder

(I-Nickel oxide Powder)

Impushana ye-NiO isetshenziswa kuma-nickel alloys, usawoti, ama-catalysts, ama-fuel cell namanye amakhemikhali kanye nama-ceramic glazes, ama-frits nama-colorants. Ukungcola okujwayelekile kuhlanganisa i-cobalt, ithusi, insimbi nesibabule ezingeni elingu-1% noma ngaphansi.

Ukuchayeka emsebenzini nakwezemvelo ku-NiO eluhlaza (NiO-g) kubikwe e-USA. Cishe amathani angama-4000 ebanga lamakhemikhali i-NiO akhiqizwa minyaka yonke.

Ocwaningweni lweminyaka emi-2 lweNational Toxicology Programme kumagundane e-F344/N, umdlavuza othile kwabikwa ngokuvuvukala okungapheli ngaphandle kwe-fibrosis. Izicubu ezithinteke kakhulu bekungamaphaphu, i-bronchial lymph nodes kanye ne-thymus. Izinguquko kulezi zitho zazifana ezilwaneni ezichayeke emazingeni aphansi e-aerosol ku-NiO-g.

I-spectroscopy ye-XPS yokulungiswa okuphezulu iqinisekise ukuba khona kwe-crystalline NiO eneziqongo eziyinhloko kumanani angu-2.41, 2.09, 1.48, 1.26 kanye no-1.21 A (d) nokuphindaphinda kwe-Ni 2p ne-O 1s. Ngaphezu kwalokho, i-XRD ibonise i-oxide yangaphandle encane ye-NiO-g embozwe i-Ni2O3 ecebile enesici noma i-Ni(OH)2 surface oxide.

Idatha yokukhishwa ye-NiO-g powder edaluliwe yanqunywa oketshezini lokwenziwa oluhambisana nemizila emibili eyinhloko yokuchayeka yobuthi be-nickel okuhlanganisa ukujuluka kokwenziwa (ASW) kanye noketshezi lokwenziwa lwe-lysosomal (ALF). Ngemva kokuchayeka, amanani e-nickel akhululiwe asuka ku-Nickel powders ancibilika ngokushesha kakhulu futhi ayephansi ku-ALF kune-ASW, okubonisa ukuthi i-nickel ekhishwe ngokuyinhloko yayiwumsebenzi wokuchithwa kwamakhemikhali kunezinqubo ze-electrochemical noma eziyinkimbinkimbi.

Izinhlamvu ezinemininingwane zezinhlayiya kanye ne-surface oxide, kuhlanganiswe nokuhlaziywa kwe-kinetics kokukhishwa kwe-nickel ezimpushaneni zensimbi ze-nickel uma kuqhathaniswa ne-nickel oxide bulk powder, kuyisinyathelo esibalulekile ekuqondeni ukuziphatha kwezimpushana zensimbi ze-nickel ezinosayizi omncane. Lolu phenyo luphinde lube ithuluzi elibalulekile lokunquma ukusebenza kabusha kwezimpushana eziyinqwaba njengendlela yokuthuthukisa ukuphepha kwazo.
