Malunga i-Rhodium
I-Rhodium iyi-ultra-rare, i-silvery-white, inzima, futhi imelana nokugqwala. I-Rhodium ine-reflection ephezulu yanoma iyiphi i-metal futhi iyinye yezinto ezibiza kakhulu ze-metal emhlabeni.
Izisebenziso
Ama-catalytic converters, ama-jewelry plating, ama-laboratory crucibles, nama-optical instruments.
Iqiniso elijabulisayo
I-80% ye-rhodium yezwe isetshenziswa kuma-catalytic converters, futhi ivame ukuba ngcono kunegolide noma i-platinum.
