sold as "magnetic hematite" yog qhov tseeb hluavtaws.
Qhov txawv ntawm hematite thiab sib nqus hematite yog dab tsi?
Manmade hematite tseem ua los ntawm hlau oxide feem ntau. Cheebtsam uas sau tias "sib nqus hematite" feem ntau yog neeg tsim, thiab cov no yog txawm tias sib nqus ntau dua li ntuj hematite, uas tsuas muaj cov hlau nplaum tsis muaj zog.… Daim ntawv no ntawm hlau oxide tuaj yeem yog hlau nplaum, ntau dua li hematite.
Yuav lub hlau nplaum lo rau hematite?
"Magnetizing" Hematite
Muaj tseeb hematite, txawm tias muaj hlau, tiag tiag muaj tsis muaj zog hlau nplaumvim tias txoj kev nws cov hlau atoms sib dhos. … Zoo li hematite tiag tiag, magnetite kuj yog hlau oxide, tab sis nws cov hlau atoms tau teem rau hauv ib yam uas ua rau nws sib nqus.
Koj tuaj yeem qhia tau li cas yog lub nplhaib hematite yog tiag?
Lub Hematite yuav tsum yog liab me ntsis hauv qab ntawm qhov chaw los yog cov hmoov Hematite yuav tsum reddish nyob rau hauv lub gemstone tiag. Tib lub tswv yim ua haujlwm nrog kev sim streak. Qhwv ib daim ntawm Hematite hla ib co unglazed plooj (porcelain) los yog ib co ntawv xuab zeb dub thiab nws yuav tsum tawm hauv cov xim liab lossis xim av.
hematite zoo li cas?
