Osmium, te huānga taumaha rawa atu i te ao
Kupu Whakataki
Ko te Osmium he huānga Rōpū VIII o te ripanga wā.Ko tetahi o te roopu konukawata (ruthenium, rhodium, palladium, osmium, iridium, platinum) huānga.Ko te tohu huānga ko Os, ko te tau ngota ko 76, ko te taumaha ngota ko 190.2.Ko te ihirangi o te kirinuku he 1 × 10-7% (papatipu), a he maha nga wa e rite ana ki etahi atu waahanga o te raupapa konukawata, penei i te konukawata konukawata, te nickel pyrite, te nickel sulfide ore, te hina-iridium osmium ore, te osmium- iridium alloy, me etahi atu. Ko te Osmium he konganuku hina-puru me te rewa o te 2700°C, he koropuputanga teitei ake i te 5300°C, me te kiato o te 22.48 g/cm3.He pakeke me te pakarukaru.Ko te osmium whakarewa nui he matū kore mahi me te pumau i roto i te hau me te taiao makuku.Ko te hautai, te paura osmium ranei ka whakahaorahia kia wha nga waikura osmium pukapuka matū i te pāmahana rūma.Ko te Osmium te nuinga o te whakamahi hei whakamaroke mo nga konukawata roopu roopu konukawata hei hanga i nga momo carbide cimented-aukati me te waikura.Ka taea te whakamahi i nga Alloys mai i te osmium me te iridium, te rhodium, te ruthenium, te konukawata, me etahi atu hei hanga hononga me nga mono o nga taputapu me nga taputapu hiko.Ka taea te whakamahi i nga koranu osmium-iridium hei tohu pene, ngira rekoata kaitakaro, kape, pivots mo nga taputapu, me etahi atu. I roto i te ahumahi takirere, ka whakanuia te kaha o te cathode ki te tuku irahiko ma te whakakoi i te kohu osmium ki runga i te kakawaea o te takirere.Ka taea te whakaheke osmium tetroxide ki te pango osmium dioxide e etahi matū koiora, no reira ka whakamahia i etahi wa hei paru kiko i roto i te miihini irahiko.Ka whakamahia ano te Osmium tetroxide ki te whakahiato waro.Ko te whakarewa Osmium he kore-paitini.Ko te Osmium tetroxide he tino whakapataritari me te paitini, a he kino nga paanga ki te kiri, ki nga kanohi me te waahanga manawa o runga.
Ngā āhuatanga ā-tinana
Ko te osmium whakarewa he hina-puru te tae, ko ia anake te whakarewa e mohiotia ana he iti ake te matotoru i te iridium.Ko nga ngota Osmium he hanganga karaihe hexagonal hexagonal, he whakarewa tino uaua.He pakeke, he pakarukaru hoki i te pāmahana teitei.Ko te HV o 1473K ko 2940MPa, he uaua ki te tukatuka.
Whakamahinga
Ka taea te whakamahi Osmium hei whakakorikori i roto i te ahumahi.I te wa e whakamahi ana i te osmium hei whakakorikori i roto i te whakahiato haukinia, te tauhohenga hauwai ranei, ka taea te whiwhi huringa teitei ake i te pāmahana iti.Mēnā ka tāpirihia he osmium iti ki te konukawata, ka taea te hanga hei scalpel koranu konukawata osmium koi.Ka taea te hanga i te koranu osmium iridium ma te whakamahi i te osmium me te nui o te iridium.Hei tauira, ko te ira hiriwa kei te pito o etahi pene koura matatau he osmium iridium alloy.Ko te koranu osmium iridium he pakeke me te kakahu-aukati, a ka taea te whakamahi hei kawe i nga karaka me nga taonga nui, me te roa o te mahi.
