Qhov sib txawv tseem ceeb ntawm cov hlau nplaum thiab hematite yogcov hlau hauv magnetite yog nyob rau hauv +2 thiab +3 oxidation xeev whereas, nyob rau hauv hematite, nws tsuas yog nyob rau hauv +3 oxidation xeev.. Magnetite thiab hematite yog cov zaub mov ntawm hlau. Ob leeg muaj hlau nyob rau hauv txawv oxidation xeev, thiab lawv yog nyob rau hauv cov ntaub ntawv ntawm hlau oxides.
Dab tsi yog qhov txawv ntawm hematite thiab magnetite?
Cov ntxhia pob zeb ua tau tiag tiag muaj cov ntsiab lus hlau ntau dua li cov ntxhia hematite. Txawm li cas los xij, thaum hematite ore feem ntau muaj qhov loj ntawm hematite, magnetite ore feem ntau tuav tsis tshua muaj siab ntawm magnetite. … Magnetite ore cov khoom sib nqus yog pab tau thaum lub sijhawm ua haujlwm no.
Koj paub qhov txawv ntawm hematite li cas?
Txawm tias hematite muaj qhov sib txawv heev, nws ib txwm ua kom muaj xim liab. Cov tub ntxhais kawm hauv cov kev qhia txog geology feem ntau xav tsis thoob thaum pom cov pob zeb muaj xim daj ua cov xim liab. Lawv kawm sai sai tias cov kab liab liab yog qhov tseem ceeb tshaj plaws rau kev txheeb xyuas hematite.
Yuav ua li cas cais hematite thiab magnetite?
Thaum cov hlau tsis muaj qib qis, uas feem ntau muaj cov hematite, siderite, thiab limonite, nyuaj rau kev kho los ntawm kev sib nqus sib nqus, tab sis lawv tuaj yeem hloov pauv mus rau ferromagnetic minerals xws li magnetite (Fe 3 O. 4) los yog maghemite (γ-Fe 2 O 3) uas haum rau hlau nplaumsib cais…
Cov cuab yeej twg tuaj yeem siv los paub qhov txawv ntawm hematite los ntawm magnetite?
Hematite kuj muaj qhov siv zog siab hauv cheeb tsam high wavenumber cheeb tsam. Vim tias magnetite tsis muaj Raman tawg nyob rau hauv cheeb tsam wavenumber no, Raman teb no tuaj yeem siv los paub qhov txawv ntawm ob lub oxides.
