Iron oxide kanye nokulungiselela yayo of izinto zokusetshenziswa amaminerali

Umuntu ngamunye nazo ekuphathweni emikhaya yazo nge lo mkhuba ukugqwala. Uyazi ukuthi lokhu umphumela namachibi yensimbi.

Njengoba kwakhiwa nokugqwala is?

Noma yimuphi umkhiqizo metal iqukethe ethile yensimbi isici :. Steel ligature njll uhlanganyela izinqubo eziningi zobuchwepheshe ngezinto ezihlukahlukene. izakhi Iron ezitholakala ungqimba lomhlaba. Lokhu metal sengezwe ngesikhathi ukukhiqizwa izinhlobo eziningi imikhiqizo, futhi ngokuphelele ukuqeda cishe ehluleka kuye, futhi kwezinye izimo lokhu akudingekile. Lo msuka, lapho ekhona sihloko metallic, ekugcineni oxidized ngendiza, umswakama, amanzi, kanye okuholela kwakhiwa phezu yensimbi oxide 3. Yebo, imikhiqizo camera nge ungqimba zokuzivikela, kodwa kulula ukuba baphule by bazithobisa yimuphi umthelela lobuchwepheshe kuthabathela ecaleni.

izakhiwo Key

Iron oxide - metal zesiliva ductile kakhulu. It ikufanele kahle izinhlobo eziningi machining: ekwakheni, ugingqe. Amandla aso ukuncibilikisa izakhi eziningi ezisetshenziswa emsebenzini wokukhiqiza Alloys eziningi. Active chemical isici baxhumana cishe zonke alulaze acid ukwakha kwakwakhe elihambisana Valence. Kodwa ukuthi iziphatha zibukele kakhulu acid kanzulu. yensimbi Pure lalungiselela ukucutshungulwa lobuchwepheshe amaminerali, okuyinto ekhona ngokuyisisekelo i-nitrous yensimbi.

uxhumano

Iron compounds yakha imigqa emibili: kwakwakhe 2-valent kanye 3-valent. Ngamunye wabo libhekene oxide yayo. Kwakheka yensimbi kwakwakhe by nokonakala e acid. yensimbi nosawoti hydrolyze 3 kakhulu, ngakho-ke abe nombala ophuzi onsundu, nakuba element Ayinambala. Iron compounds kabanzi yokusansimbi njenge-ejenti ekunciphiseni, emnothweni kazwelonke ukulawula izinambuzane basembonini yendwangu, njll Anhydrous yensimbi oxide 2 ibhalwe kusuka 3 by ukunciphisa oxide njengoba powder black, kuyilapho ukulungiswa yensimbi oxide 3 kwenzeka calcining yensimbi hydroxide 3. oxides umsuka ukuthola nosawoti yensimbi. Kusekhona omncane owaziwa ngokuthi enkompolo acid enkompolo nge Valence of +6. Lapho tho oxide 3 kwakhiwa ferrites futhi ferrates, entsha, kwakwakhe wafunda okwamanje kahle.

Ukwanda ngokwemvelo

I element echazwe futhi compounds zalo esakazwa ngokwemvelo. Ngesimo obomvu, limonite yensimbi oxide 3 kwenzeka ngesimo magnetite - Fe3O4. Ukuze kukhiqizwe sulfuric acid yensimbi pyrites (sulphide) isetshenziswa. Oxides luwumthombo oyinhloko zensimbi steel. Steel nensimbi cishe ukwakheka efanayo, umehluko kuphela okuqukethwe carbon. Iron Alloys equkethe esingaphansi 2.14% carbon, lezinsimbi babizwa, futhi ezingaphezu kuka-2.14% - yensimbi. Lokhu ukusatshalaliswa asifanele lezinsimbi eziyinkimbinkimbi ezifana ingxubevange, ngoba akheke eyinkimbinkimbi zinezikhathi khona izakhi ezengeziwe.
