Osmium, ntho e boima ka ho fetisisa lefatšeng
Selelekela
Osmium ke karolo ea sehlopha VIII ea tafole ea periodic.E 'ngoe ea lihlopha tsa platinum (ruthenium, rhodium, palladium, osmium, iridium, platinum).Letšoao la element ke Os, nomoro ea athomo ke 76, 'me boima ba athomo ke 190.2.Likahare tsa bokaholimo ke 1 × 10-7% (boima), 'me hangata li lumellana le likarolo tse ling tsa letoto la platinum, joalo ka ore ea mantlha ea platinamo, nickel pyrite, nickel sulfide ore, gray-iridium osmium ore, osmium- iridium alloy, joalo-joalo Osmium ke tšepe e bohlooho-putsoa e nang le ntlha e qhibilihisang ea 2700 ° C, ntlha e belang e fetang 5300 ° C, le boima ba 22.48 g / cm3.E thata ebile e brittle.Osmium ea tšepe e ngata ha e sebetse ka lik'hemik'hale 'me e tsitsitse moeeng le tikolohong e mongobo.Osmium e seponche kapa e phofshoana e tla tšeloa butle-butle ho li-oxidized tse 'nè tsa Chemicalbook osmium mocheso oa kamore.Osmium e sebelisoa haholo-holo e le sesebelisoa se thatafatsang bakeng sa li-alloys tsa tšepe tsa sehlopha sa platinum ho etsa li-carbide tse samente tse sa senyeheng le tse sa jeng.Li-alloys tse entsoeng ka osmium le iridium, rhodium, ruthenium, platinum, joalo-joalo li ka sebelisoa ho etsa likhokahano le li-plug tsa lisebelisoa le lisebelisoa tsa motlakase.Li-alloys tsa Osmium-iridium li ka sebelisoa e le malebela a pene, lisebelisoa tsa ho rekota, li-compass, li-pivots bakeng sa lisebelisoa, joalo-joalo indastering ea li-valve, bokhoni ba cathode ea ho ntša li-electrone bo matlafatsoa ke ho fokotsa mouoane oa osmium holim'a filament ea valve.Osmium tetroxide e ka fokotsoa hore e be black osmium dioxide ka lintho tse itseng tsa baeloji, kahoo ka linako tse ling e sebelisoa e le letheba la linama ho electron microscopy.Osmium tetroxide e boetse e sebelisoa ho organic synthesis.Osmium tšepe ha e na chefo.Osmium tetroxide e teneha haholo ebile e chefo, 'me e na le litlamorao tse mpe letlalong, mahlo le pampiring e kaholimo ea ho hema.
Lintho tsa 'mele
Osmium ea tšepe e na le 'mala o moputsoa o moputsoa 'me ke eona feela tšepe e tsejoang ka hore ha e teteane ho feta iridium.Liathomo tsa Osmium li na le sebopeho se teteaneng sa kristale sa hexagonal, e leng tšepe e thata haholo.E thata ebile e brittle mocheso o phahameng.HV ea 1473K ke 2940MPa, eo ho leng thata ho e sebetsa.
Tšebeliso
Osmium e ka sebelisoa e le mohloli oa matla indastering.Ha o sebelisa osmium e le mohloli oa ammonia synthesis kapa hydrogenation reaction, phetoho e phahameng e ka fumanoa ka mocheso o tlase.Haeba osmium e nyenyane e kentsoe platinum, e ka etsoa hore e be scalpel e thata le e bohale ea osmium platinum alloy scalpel.Osmium iridium alloy e ka etsoa ka ho sebelisa osmium le tekanyo e itseng ea iridium.Ka mohlala, letheba la silevera le ntlheng ea lipene tsa khauta tse tsoetseng pele ke osmium iridium alloy.Osmium iridium alloy e thata ebile ha e sebetse, 'me e ka sebelisoa e le ho tsamaisa lioache le lisebelisoa tsa bohlokoa, ka bophelo bo bolelele ba ts'ebeletso.
