Izvo hazvina kunyatsogadziriswa kwemaschmetal, asi inowanzogadzirwa inenge inenge 50 muzana cerium uye 25 muzana lanthanum ine zviduku zvishoma neodymium, praseodymium uye imwe nheyo dzisina kuwanikwa pasi dzinokwana.
Nekusikwa kwekutanga kwepakutanga kubva kuneonazite ore, nyika isingawanzogadziriswa yezvigadzirwa zvemidziyo yakaberekerwa, ichigadzirisa nzira yekuzvimirira uye yekuchenesa kwenyika dzakawanda dzisingashamisi.
Proper Properties
Pakati pese, mischmetal iri nyore uye inotyisa. Zvisinei, nokuti pasi risingawanzoiti nyore kushivirira uye kunwa hydrogen uye nitrogen, zvakaoma zvikuru kubudisa samuko yakakwana yakakwana yezvinyorwa kuitira kuti iongorore iyo yemagetsi uye magetsi.
Maererano neJiangxi Xinji Metals, mutungamiri wekuChinese anonyanya kushandiswa kwezvinhu zvisina kunaka, kunyange zvisingashamisi pasi zvigadzirwa zvakapiwa kusvika 99.999% zvekutsvaga kwekutengeserana zvingangova ne 99.99% isiri pasi pasi resimbi muhutano hwakagadziriswa, uye kusvika kusvika ku10 000 chikamu pamamiriyoni asina kuchena mumhepo.
Izvi zvakasvibisa zvinokonzera maitiro ekutadza uye microstructural inclusions iyo inopisa simba pamusoro pesimba, kuoma, ductility uye conductivity zvinhu. Somugumisiro, hapana chinhu chakakosha uye chechokwadi chemamiriro epfuma chaiwo pane zvakasiyana-siyana zvekutengeserana zvischmetals inobudiswa nemabhizimisi kana mumabhuku ekutsvakurudza.
Nhoroondo
Mischmetal pakutanga yainzi Auer's metal, mushure meCarl Auer von Welsbach uyo akasika gorosi kubva pane zvakasara kubva pane zvaakaedza pakugadzira thorium-powered light-mantle muna 1885.
Mhuka yake ye thorium yaiva senizite yejecha, iyo imwe inenge 90-95% yakaumbwa nedzimwe nyika dzisati dzisati dzawanikwa. Hapana chimwe chezvizvi panguva iyoyo chaiva nehuwandu hwekutengeserana.
Pakazosvika 1903, von Welsbach akanga agadziridza fusion ye electrolysis kuti abudise pasina-cerium alloy isina makumi matatu nezana yesimbi . Iko kuwedzerwa kwesimbi kunowedzera kuoma kukuru kune cerium, iyo inonzi pyrophoric rare earth.
Akanga akasika Auermetall, inozivikanwa se ferrocerium, iyo ndiyo nyaya yekushandisa inoshandiswa kune marimu mumoto anotanga moto uye lighters.
Kubva pane izvi zvakawanikwa, kubva kuWelsbach akaziva kuti aigona kuparadzanisa nyika dzakasiyana-siyana dzisina kuwanikwa kubva kune imwe yero inoshandisa magetsi. Nokunyatsoshandisa shanduko dzakasiyana-siyana dzepasi zvakasiyana-siyana zvisingawaniki, iye aigona kuzvisiyanisa kubva kune maitiro echloride. Ichi chaiva kutanga kwebasa risina tsvina yepasi rese - zvino izvo zvakasiyana-siyana zvakachena zvinogona kuongororwa uye zvinoshandiswa kune zvitsva zvekushandisa.
Mischmetal kuMusika uye Munzvimbo
Mischmetal haina kutengeswa sechinhu chinowanikwa pakukurukurirana kukuru asi inopedzwa kuburikidza nemikana yakawanda yemudhizimusi. China ndicho chibereko chikuru chepasi, kusanganisira mischmetal alloy.
Mischmetal inoshandiswa zvakananga mumabasa ekushanda:
- Sezvo oxygen getter mukuvhara tube tube.
- Mune mabhethri anovimba nesimbi ye hydride teknolojia.
- Semhepo inotanga kupisa moto nemirazvo, uyewo mumabhaisiro emitambo yakasiyana.
- Nezvigadzirwa zvesimbi uye zvisingasviki kuti vashandise kugadziriswa uye magetsi mumamwe maarloys.
