Malunga I-Rhenium
I-Rhenium iyinsimbi emnyama-emnyama, enzima nengxenye yesithathu ephakeme kakhulu yokuncibilika. Yabe yingxenye ephelile eqinile etholakalayo. Ukukhiqizwa konyaka kwehlabathi kungaphansi kwamathani ayi-50 kuphela.
Izisebenziso
I-jet engine superalloys, i-petroleum refining catalysts, thermocouples, kanye ne-mass spectrometry filaments.
Iqiniso elijabulisayo
I-rhenium yayiyingxenye ephelile etholakalayo etholakalayo (1925) futhi cishe ama-50 tons kuphela akhiqizwa ngonyaka emhlabeni wonke.
