Iron oxide da kuma shirye-shiryen na ma'adinai raw kayan

Kowane mutum karo a gudanar da su gidaje da sabon abu na tsatsa. Ya san cewa wannan shi ne sakamakon hadawan abu da iskar shaka na baƙin ƙarfe.

Kamar yadda tsatsa da aka kafa?

Wani karfe samfurin ƙunshi wani adadin na baƙin ƙarfe kashi :. Karfe ligature da dai sauransu Yana halarci yawa fasaha matakai na daban-daban karafa. Iron abubuwa samu a duniya ta ɓawon burodi. Wannan ƙarfe aka kara a lokacin samar da nau'o'in kayayyakin, da kuma gaba daya rabu da kusan gaza shi, da kuma a wasu lokuta wannan ba lallai ba ne. Wannan kashi, a lokacin da ba a ƙarfe labarin, ƙarshe oxidized da iska, danshi, da ruwa, da kuma sakamakonsa kafa a kan surface na baƙin ƙarfe oxide ne 3. Hakika, kayayyakin mai rufi da m Layer, amma yana da sauki karya da biyayya wani fasaha tasiri daga gefe.

key Properties

Baƙin ƙarfe oxide - azurfa karfe ne sosai ductile. Yana lends kanta da kyau zuwa yawa iri machining: ƙirƙirãwa, mirgina. Its ikon soke yawa abubuwa yadu amfani a samar da dama gami. Active sinadari interacts tare da kusan dukkan tsarma acid don ya samar da wani fili m valence. Amma shi behaves sosai passively a mayar da hankali acid. Pure baƙin ƙarfe aka shirya da fasaha aiki na ma'adanai, wanda yake ba a gaske wani oxide na baƙin ƙarfe.

sadarwa

Iron mahadi samar biyu layuka: fili 2-valent da kuma 3-valent. Kowace daga cikinsu ne halin da oxide. Kafa baƙin ƙarfe fili ta rushe a acid. baƙin ƙarfe salts hydrolyze 3 karfi, saboda haka suna da wani yellow-kasa-kasa launi, ko da yake kashi ne colorless. Iron mahadi ana amfani da ko'ina a metallurgy a matsayin rage wakili, a cikin kasa tattalin arzikin a cikin iko da kwari a cikin yadi masana'antu, da dai sauransu. Anhydrous baƙin ƙarfe oxide 2 da aka shirya daga 3 da rage oxide a matsayin baki foda, alhãli kuwa shiri na baƙin ƙarfe oxide 3 faruwa da calcining baƙin ƙarfe hydroxide 3. oxides underlie samu baƙin ƙarfe salts. Akwai har yanzu kadan da aka sani a matsayin acid fili da fili da valence na +6. Lokacin da Fused oxide 3 kafa ferrites da ferrates, sabon, ba tukuna sosai karatu fili.

Yaduwar a cikin yanayi

The bayyana kashi da ta mahadi aka yadu rarraba a yanayi. A cikin irin ja, limonite baƙin ƙarfe oxide 3 auku a cikin nau'i na magnetite - Fe3O4. Domin samar da sulfuric acid baƙin ƙarfe pyrites (sulphide) da ake amfani. Oxides ne babban tushen baƙin ƙarfe da karfe. Karfe, da baƙin ƙarfe da kimanin guda abun da ke ciki, da kawai bambanci ne carbon ciki. Iron gami dauke da kasa da 2.14% carbon, steels ake kira, kuma fiye da 2.14% - baƙin ƙarfe. Wannan rarraba ba dace da hadaddun steels kamar gami, saboda suna da wani hadadden tsarin da kuma halin gaban ƙarin abubuwa.
