Iron oxide kunye nolungiselelo lwalo kwezinto kwezimbiwa ekrwada

Umntu ngamnye nazo kulawulo lemizi yabo ngxaki yokusetyenziswa irusi. Uyazi ukuba oku kubangelwa igcwala yentsimbi.

Njengoko umhlwa kwakheka?

Nayiphi na imveliso metal iqulethe isixa esithile isiqalelo yentsimbi :. Steel ligature njl njl inxaxheba kwiinkqubo ezininzi zobugcisa ngeentlobo ezahlukeneyo zesinyithi. izinto Iron eyafunyanwa kolu qweqwe lomhlaba. Le metal idityaniswa ngexesha imveliso iintlobo ezininzi iimveliso, kwaye ngokupheleleyo balahle phantse siyayiswela intliziyo, kwaye kwezinye iimeko oku kuyimfuneko. Le element, xa ndikho kwinqaku sisinyithi ke, ekugqibeleni oxidized-moya, ukufuma, amanzi, nto leyo kwakheka kwi kwamanzi oxide intsimbi ithe 3. Kakade ke, iimveliso isale ngomaleko yokhuselo, kodwa kulula ukuba aphule nezikhundla naliphi na ifuthe lobugcisa kwicala.

iipropati key

Iron oksayidi - metal nesilivere ductile kakhulu. Ukuba akunjalo kakuhle ngokwayo ukuba iintlobo ezininzi machining: elibenze, kaloliwe. ikhono layo ukunyibilika izinto ezininzi ezisetyenziswayo kakhulu ekuveliseni aluminium ezininzi. Active element chemical ahlangana phantse nabo bonke yaze yangxenga ifuthe lomanyano asidi ukwenza compound engqinelanayo Valence. Kodwa iziphatha nje kunene asidi kanzulu. intsimbi olunyulu eziqulunqwe processing lobugcisa izimbiwa, nto leyo ekhona ngokwesiseko oxide yentsimbi.

uxhulumaniso

iikhompawundi Iron zakha imikrozo emibini: compound 2-valent ze-valent 3. Ngamnye kubo luphawulwa oxide yayo. Senziwe compound intsimbi ngu zokuchithwa in asidi. iityuwa zentsimbi hydrolyze 3 kakhulu, ngoko ube umbala otyheli-omdaka, nangona sakhi enemibala. iikhompawundi Iron ezisetyenziswa yokunyibilikisa isinyithi njenge arhente ekunciphiseni, kuqoqosho wesizwe kolawulo izinambuzane kushishino lwamalaphu kweli, njl iron oxide Anhydrous 2 ilungisiwe ukususela 3 ekunciphiseni oxide ibe ngumgubo emnyama, ngoxa ukulungiselela oxide yentsimbi 3 kwenzeka ngokuthi calcining isinyithi hayidroksayidi 3. Oxides ezisisiseko ukufumana iityuwa zentsimbi. Kusekho encinane eyaziwa ngokuba umchiza acid kunye ezimbaxa kunye Valence ka +6. Xa tho oksayidi 3 kwasekwa ferrites kunye ferrates, amatsha, babefunda kodwa kakuhle kakhulu ezimbaxa.

Ubukho endalweni

Isiqalelo wachaza kunye nemixube yayo ezisasazwa kwindalo. Xa uhlobo ebomvu, limonite yentsimbi oxide 3 kwenzeka ngohlobo magnetite - Fe3O4. Kuba ukuveliswa kwe-sulphuric acid pyrites yentsimbi (sulphide) iyasetyenziswa. Oxides zingumthombo engundoqo zentsimbi kunye ngentsimbi. Steel kunye nentsimbi unamalunga ekwakhiweni enye, umahluko kuphela umxholo carbon. aluminiyamu Iron equlathe ngaphantsi kwe 2.14% carbon, yodidi babiziweyo, kwaye ngaphezu kwama-2.14% - yentsimbi. Le unikezelo ezingafanelekanga yodidi ezintsonkothileyo ezifana ingxubevange, ngenxa yokuba isakhiwo ezinokuntsonkotha luphawulwa ubukho izinto ezongezelelweyo.
