ʻO ka pauka Rhodium he paʻakikī a he palupalu, he mana noʻonoʻo ikaika, a he palupalu loa ma lalo o ka hoʻomehana. He kūpaʻa kemika maikaʻi ʻo Rhodium. Loaʻa i ka Rhodium ka pale oxidation maikaʻi a hiki ke mālama i ka nani i ka lewa no ka manawa lōʻihi.

ʻO ka ʻoihana kaʻa ka mea hoʻohana nui loa i ka pauka rhodium. I kēia manawa, ʻo ka hoʻohana nui ʻana o ka rhodium i ka hana kaʻa kaʻa kaʻa exhaust catalyst. ʻO nā ʻāpana ʻoihana ʻē aʻe e ʻai ana i ka rhodium ʻo ia ka hana aniani, ka hana ʻana i nā niho niho, a me nā huahana nani.

Me ka hoʻomau mau ʻana o ka ʻenehana cell cell a me ka ulu ʻana o ka ʻenehana kaʻa wahie, e hoʻomau ka nui o ka rhodium i hoʻohana ʻia i ka ʻoihana kaʻa.
