Kana saizi yeFe2O3 Iron(III) oxide idiki kusvika nanometer(1~100nm), iyo atomiki nhamba yepasi, nzvimbo chaiyo uye simba repamusoro resimbi oxide zvidimbu zvinowedzera zvakanyanya nekudzikira kwesaizi, iyo inoratidza maficha ediki saizi maitiro, quantum saizi maitiro, pamusoro pekuita uye macroscopic quantum tunneling maitiro. Iyo ine yakanaka optical zvivakwa, magineti zvivakwa uye catalytic zvivakwa nezvimwe, iyo ine yakafara application muminda yekunyudza mwenje, mushonga, magineti midhiya uye catalysis.
1. Kushandiswa kwe nano-iron oxide mune magineti zvinhu uye magineti ekurekodha zvinhu
Nano Fe2O3 ine yakanaka magineti zvivakwa uye kunaka kuoma. Oxymagnetic zvinhu zvinonyanya kusanganisira yakapfava magineti iron oxide (α-Fe2O3) uye magineti yekurekodha iron oxide (γ-Fe2O3). Magnetic nanoparticles ane hunhu hweimwe magineti domain chimiro uye yakakwirira yekumanikidza simba nekuda kwehukuru hwayo hudiki. Kuzvishandisa kugadzira magineti ekurekodha zvinhu zvinogona kuvandudza chiratidzo-kune-ruzha reshiyo.
2. Kushandiswa kwenano iron oxidemumapendi uye machira Mu pigments, nano iron oxide inonziwo transparent iron oxide (iron inopinda). Izvo zvinodaidzwa kujeka hazvireve zvakananga kune macroscopic transparency yezvimedu pachazvo, asi zvinoreva kupararira kwe pigment particles mu organic phase kuita layer yependi firimu (kana mafuta firimu). Kana chiedza chikavhenekerwa pafirimu yepende, kana isingashanduki yepakutanga Kuburikidza nefirimu yepende, zvikamu zvepigment zvinonzi zviri pachena. Iyo inoonekera iron oxide pigment ine yakakwira chroma, yakakwira tinting simba uye kujeka kwepamusoro, uye ine kukuya kwakanaka uye kupararira mushure mekunyanya kurapwa kwepamusoro. Transparent iron oxide pigments inogona kushandiswa kuoira uye alkyd, amino alkyd, acrylic uye mamwe pendi kugadzira pendi yakajeka, ine yakanaka yekushongedza zvinhu. Iyi pendi yakajeka inogona kushandiswa yega kana kusanganiswa nemamwe organic color pigment pastes. Kana shoma shoma yearuminiyamu isingayangarara poda paste yakawedzerwa, inogona kugadzirwa musimbi inogadzirisa pendi ine flickering feeling; inofananidzwa nemaprimers emavara akasiyana , Inogona kushandiswa mukushongedza zviitiko nepamusoro zvinodiwa, senge mota, mabhasikoro, zviridzwa, mamita, uye huni. Iron-transmitting pigment kunyura kwakasimba kwe ultraviolet mwenje kunoita kuti ive ultraviolet shielding agent mumapurasitiki, uye inoshandiswa mukurongedza mapurasitiki sezvinwiwa nemishonga. Nano Fe2O3 ine zvakare yakafara tarisiro yekushandisa mune electrostatic shielding coatings, uye Fe3O2 nano coatings ane yakanaka electrostatic shielding akabudirira kugadzirwa. Nanoparticles akadaro ane semiconductor zvivakwa ane yakakwirira conductivity pane yakajairwa oxides pakamuri tembiricha, uye nekudaro inogona kutamba electrostatic shielding basa.
3. Kushandiswa kwe nano-iron oxide mu catalyst Nano-iron oxide ndiyo yakanaka kwazvo inogadzirisa. Hollow spheres yakagadzirwa nano-α-Fe2O3 yakayangarara pamusoro pemvura yakasviba ine organic zvinhu. Kushandisa chiedza chezuva kushatisa organic zvinhu zvinogona kukurumidzira nzira yekuchenesa mvura yetsvina. Iyi nzira inoshandiswa neUnited States, Japan, nezvimwewo kugadzirisa kusvibiswa kunokonzerwa nekurasika kwemafuta ekumahombekombe. Nano-α-Fe2O3 yakashandiswa zvakananga sechinhu chinokonzeresa oxidation, kuderedza uye kuumbwa kweakakwira molecular polymers. Iyo nano-α-Fe2O3 catalyst inogona kuwedzera kutsemuka kwepetroleum ne1 kusvika ku5 nguva, uye kumhanya kwekupisa kweakasimba mapropellants akagadzirwa nayo sechinhu chinopisa chinogona kuwedzera ne1 kusvika ku10 nguva zvichienzaniswa nekumhanya kwekupisa kweakajairika propellants. . Maroketi nemakomba anobatsira zvikuru.
