Ukuhlanzeka okuphezulu kwe-rhenium metal powder iyimpushana yensimbi empunga ekhanyayo eyenziwe ngekristalu eyodwa ehlanganisiwe. Siyaqinisekisa ukuthi imikhiqizo yethu inokuhlanzeka okuphezulu kakhulu, ukuzinza, kanye nekhwalithi eqinisekisiwe. I-Rhenium metal powder ingasetshenziswa emikhiqizweni ecishe iqedwe, njengamapuleti e-anode asetshenziswa kwezokwelapha. Insimbi ye-Rhenium iqinile kakhulu, ayigugi, imelana nokugqwala, futhi ibukeka njengeplatinamu. I-rhenium ehlanzekile ithambile futhi inezindawo ezinhle zokusebenza. I-Rhenium inendawo yokuncibilika engu-3180 ℃, ikleliswe endaweni yesithathu kuzo zonke izici ngemva kwe-tungsten ne-carbon. Iphuzu layo elibilayo lingu-5627 ℃, libalwa kuqala kuzo zonke izakhi. Iyancibilika ezixazululweni ze-nitric acid noma i-hydrogen peroxide futhi ayincibiliki ku-hydrochloric acid ne-hydrofluoric acid. I-Rhenium, njengensimbi eyivelakancane enezinhlelo ezikhethekile, idlala indima engenakuthathelwa indawo kuma-alloys okushisa okuphezulu ezinjini ze-aerospace. I-Rhenium isetshenziselwa ukukhiqiza ama-alloys e-crystal high-temperature esebenza kakhulu futhi isetshenziswa kuma-blades ezinjini ze-aerospace. Iwumthombo obalulekile wamasu wezinto ezibonakalayo. I-Rhenium izinzile kakhulu emazingeni okushisa aphezulu, inomfutho we-vapor ophansi, ukumelana nokugqoka, kanye nekhono lokumelana nokugqwala kwe-arc, okuyenza ibe yinto enhle kakhulu yokuhlanza okuzenzakalelayo kokuthintana nogesi.

Isicelo:

Isetshenziswa njengesengezo se-rhenium high-temperature alloys, i-surface coating yezinjini zamarokhethi nezinjini zesathelayithi, izinto ezisebenza nge-athomu, i-thermal ionization mass spectrometer, isifutho sempushana.
Imikhiqizo ye-rhenium efana nezinhlamvu ze-rhenium, imicu ye-rhenium, amapuleti e-rhenium, izinti ze-rhenium, ama-rhenium foil, nezintambo ze-rhenium yizinto eziyisisekelo.

Ukucaciswa Kwekhemikhali:

Re-standard≥99.99%(Ibalwa ngendlela yokukhipha, ngaphandle kwama-elementi egesi)Re-ultrapure≥99.999%(Ibalwa ngendlela yokukhipha, ngaphandle kwama-elementi egesi)oxygen: ≤600ppm

Usayizi wezinhlayiyana: -200 mesh, D50 20-30um noma ngokuya ngesidingo sekhasimende hlinzeka ngombiko wokuhlola ukusatshalaliswa kwezinhlayiyana ze-laser noma izithombe ze-SEM njengesicelo ngasinye sekhasimende.

Ukuhlaziywa kwamakhemikhali okujwayelekile
