Malunga Osmium
I-Osmium iyinsimbi eqinile, eqinile, emnyama-emnyama. I-Osmium tetroxide inamandla amakhulu okungcola. Insimbi inzima kakhulu futhi imelana nokugqwala.
Izisebenziso
I-nibs yepensela, izixhumanisi ze-electric, amathuluzi axhunywe, kanye ne-catalyst (osmium tetroxide).
Iqiniso elijabulisayo
I-Osmium iyingxenye eqinile kakhulu, cishe izikhathi ezimbili eziqinile kune-lead. Inyawo elilinganayo lizoyisisindo esingaphezu kuka-1,400 ama-pound.
