Budada birta rhenium ee nadiifka sare ah waa budo bir cawlan khafiif ah oo laga sameeyay hal kiristaalo agglomerated. Waxaan dammaanad qaadaynaa in alaabadayadu ay leeyihiin nadiifnimada ugu sarreysa, xasilloonida, iyo tayada la shahaadeeyay. Budada birta Rhenium waxaa loo isticmaali karaa alaabada dhammaatay, sida taarikada anode ee loo isticmaalo codsiyada caafimaadka. Birta Rhenium waa mid aad u adag, u adkaysata, daxalka u adkaysata, waxayna leedahay muuqaal la mid ah platinum. Rhenium saafi ah waa jilicsan waxayna leedahay sifooyin farsamo oo wanaagsan. Rhenium waxay leedahay dhibic dhalaalaysa oo ah 3180 ℃, oo kaalinta saddexaad ka gashay dhammaan curiyeyaasha ka dib tungsten iyo kaarboon. Meesha ay ku karsanayso waa 5627 ℃, oo kaalinta koowaad ka gashay dhammaan walxaha. Waxay ku milmi kartaa xalalka nitric acid ama hydrogen peroxide oo aan lagu milmin hydrochloric acid iyo hydrofluoric acid. Rhenium, sida bir naadir ah oo leh codsiyo gaar ah, waxay ka ciyaartaa door aan la bedeli karin ee daawaha heerkulka sare ee matoorada hawada. Rhenium waxaa loo isticmaalaa in lagu soo saaro halbeeg heerkul sare leh oo hal crystal ah oo wax qabad sare leh waxaana lagu dabaqaa matoorada hawada hawada. Waa kheyraad agab cusub oo istiraatiiji ah oo muhiim ah. Rhenium waa mid aad u deggan heerkulka sare, cadaadiska uumiga hooseeya, xirto caabbinta, iyo awoodda iska caabinta arc corrosion, taasoo ka dhigaysa walxo aad u fiican oo si toos ah loogu nadiifiyo xiriirada korantada.

Codsiga:

Loo isticmaalo sida wax lagu daro rhenium alloys heerkul sarreeya, daahan dusha sare ee matoorada gantaallada iyo matoorada dayax-gacmeedka, walxaha falcelinta atomiga, spectrometer mass ionization kulaylka, buufin budada ah
Alaabooyinka Rhenium sida granules rhenium, strips rhenium, taarikada rhenium, ulaha rhenium, foils rhenium, iyo fiilooyinka rhenium ayaa ah alaabta aasaasiga ah.

Tilmaamaha Kiimikada:

Dib-u-heerka ≥99.99%

Cabbirka walxaha: -200 mesh, D50 20-30um ama sida ku xusan baahida macmiilku waxay bixiyaan warbixinta tijaabada qaybinta qaybinta qaybinta laser ama sawirada SEM sida codsiga macmiilka.
