Pigment yeruvara rweIron Oxide

Nhamba yeCAS: 12227-89-3
Fomura yeMolecular: Fe3O4
Kurema kwemamorekuru: 231.53
Okisijeni yesimbi nhema (Magnetite)
Iron oxide nhema inoshandiswa senzvimbo yeFe mukushandiswa kweceramic, kunyanya muglazing uko mutengo neruvara rwayo dema raw zvakakosha. Iron oxide inopa ruvara muglazing mushure mekupiswa pakupisa kwakanyanya. Kuchena kwakanyanya, simbi shoma ine magiredhi emhando yeheavy metal inowanikwa. Zvigadzirwa zvedu zveupfu hwesimbi nhema zvine 98% kana kupfuura Fe3O4. Magnetite 99% Fe3O4 (Black Iron Oxide)
Kushandiswa: Kuvaka, Kupenda & Kupenda, Inki, Rabha, Plastiki, nezvimwewo.

Upfu hwesimbi nhema hunoshandiswawo semushonga wekupenda wezvinhu zvakasiyana-siyana zvisiri zveceramic.
Mamwe mavara esimbi anoshandiswa zvakanyanya mumunda wezvekushongedza. Anoonekwa seasina chepfu, anodzivirira hunyoro, uye asingabudisi ropa. Ma oxide esimbi akasarudzwa kuti ashandiswe muzvekushongedza anogadzirwa nenzira yekugadzira kuitira kudzivirira kusvibiswa kunowanzo kuwanikwa muma oxide esimbi anowanikwa zvakasikwa.
Black iron oxide kana magnetite inoshandiswawo kudzivirira ngura. Black iron oxide inoshandiswawo mumapendi anodzivirira ngura (anoshandiswa mumabhiriji akawanda).
Ma oxide esimbi anoshandiswa semushonga wekusiyanisa muMagnetic Resonance Imaging, kupfupisa nguva dzekuzorora kweproton, (T1, T2 naT2). Ma super paramagnetic contrast agents anoumbwa ne crystalline magnetic core isinganyungudike mumvura, inowanzova magnetite (Fe3O4). Avhareji yepakati pepakati inotangira pa4 kusvika ku10 nm. Iyi crystalline core inowanzo tenderedzwa ne dextrin kana starch derivatives. Hukuru hwese hwe particle hunoratidzwa seavhareji ye hydrated particle dayamita.
