Rare earth elementsivo pachavo vane hupfumi hwemagetsi zvimiro uye vanoratidza akawanda optical, magetsi, uye magineti zvivakwa. Mushure me isingawanzo pasi nanomaterialization, inoratidza akawanda hunhu, senge diki saizi maitiro, yakakwira chaiyo yepamusoro maitiro, quantum athari, yakanyanya kusimba optical, magetsi, magineti zvivakwa, superconductivity, yakakwira makemikari chiitiko, nezvimwe, izvo zvinogona kuvandudza zvakanyanya mashandiro uye basa. yezvishandiso uye gadzira zvinhu zvitsva zvakawanda. Ichaita basa rakakosha muminda yepamusoro-soro senge optical materials, light-emitting materials, crystal materials, magnetic materials, battery materials, Electroceramics, engineering ceramics, catalysts, nezvimwewo?
1, Tsvagiridzo yazvino yekuvandudza uye masimi ekushandisa
1. Rare earth luminescent material: Rare earth nano fluorescent powder (ruvara rweTV poda, rambi poda), nekuvandudzwa kwechiedza chinopenya, chichaderedza zvikuru huwandu hwepasi risingawanzoshandiswa. Kunyanya kushandisaY2O3, Eu2O3, Tb4O7, CeO2, Gd2O3. Kukwikwidza Zvishandiso Zvitsva zvePamusoro Tsanangudzo Ruvara Terevhizheni.?
2. Nano superconducting zvinhu: YBCO superconductors yakagadzirirwa kushandisa Y2O3, kunyanya zvinyoro zvemufirimu zvinhu, zvine maitiro akadzikama, simba repamusoro, kugadzirisa nyore, pedyo nedanho rinoshanda, uye tarisiro yakafara.?
3. Kashoma pasi nano magineti zvinhu: inoshandiswa kune magineti memory, magineti fluid, giant magnetoresistance, zvichingodaro, inonatsiridza zvakanyanya mashandiro, ichiita midziyo yepamusoro-inoshanda uye miniaturized. Semuenzaniso, oxide giant magnetoresistance zvinangwa (REMnO3, nezvimwewo).?
4. Rare Earth high-performance ceramics: Electroceramics (electronic sensors, PTC materials, microwave materials, capacitors, thermistors, etc.) yakagadzirirwa ne-ultra-fine kana nanometer Y2O3, La2O3, Nd2O3, Sm2O3, nezvimwewo, iyo ine magetsi emagetsi, inopisa. zvivakwa, uye kugadzikana kwakagadziridzwa zvakanyanya, chinhu chakakosha chekusimudzira zvigadzirwa zvemagetsi. Ceramics sintered pane tembiricha yakaderera, senge nano Y2O3 uye ZrO2, ine simba rakasimba uye kuomarara, uye inoshandiswa mumidziyo isingapfeki senge mabheya uye maturusi ekucheka; Kuita kwema multilayer capacitors uye microwave zvishandiso zvakagadzirwa nano Nd2O3, Sm2O3, nezvimwe zvakavandudzwa zvakanyanya.?
5. Rare Earth nanocatalysts: Muzviitiko zvakawanda zvemakemikari, zvisingawanzoitiki pasi pevhu zvinoshandiswa. Kana isingawanzo pasi nanocatalysts yakashandiswa, basa ravo rinokurudzira uye kushanda zvakanaka kuchavandudzwa zvikuru. Iyo yazvino CeO2 nano poda ine zvakanakira basa repamusoro, mutengo wakaderera uye hupenyu hurefu hwesevhisi mumotokari inopedza kuchenesa, uye yakatsiva mazhinji ematare anokosha, nekushandiswa kwegore negore kwezviuru zvematani.?
6. Kashoma pasi ultraviolet absorber:Nano CeO2poda ine kunyura kwakasimba kwemwaranzi yeultraviolet, uye inoshandiswa muzvizoro zvezuva, mafiber ezuva, girazi reMotokari, nezvimwe?
7. Rare Earth precision polishing: CeO2 ine yakanaka yekupuruzira mhedzisiro pagirazi nezvimwe zvinhu. Nano CeO2 ine high polishing precision uye yakashandiswa mune liquid crystal displays, silicon wafers, glass store, etc. yakawedzera kukosha, yakakura application renji, yakakura kugona, uye inovimbisa kwazvo kutengeserana tarisiro.?
2, Kugadzirira tekinoroji
Parizvino, kugadzirwa uye kushandiswa kwemananomaterials kwakwezva kutarisa kubva kunyika dzakasiyana siyana. China nanotechnology inoramba ichifambira mberi, uye kugadzirwa kwemaindasitiri kana kugadzirwa kwekuyedza kwakabudirira kuitwa mu nanoscale SiO2, TiO2, Al2O3, ZnO2, Fe2O3 uye zvimwe zvinhu zvehupfu. Nekudaro, iyo yazvino maitiro ekugadzira uye yakakwirira mitengo yekugadzira ndiko kushaya simba kwayo kunouraya, izvo zvinokanganisa kupararira kwekushandiswa kwemananomaterials. Naizvozvo, kuramba uchivandudza kunodiwa.?
Nekuda kwechimiro chakakosha chemagetsi uye yakakura Atomic radius yezvinhu zvisingawanzo pasi, zvimiro zvavo zvemakemikari zvakasiyana kubva kune zvimwe zvinhu. Naizvozvo, nzira yekugadzirira uye mushure mekurapa tekinoroji yeasingawanzo pasi nano oxides zvakare akasiyana nezvimwe zvinhu. Nzira huru dzekutsvagisa dzinosanganisira:?
1. Precipitation method: kusanganisira oxalic acid precipitation, carbonate precipitation, hydroxide precipitation, homogeneous precipitation, complexation precipitation, etc. Chinhu chikuru cheiyi nzira ndechokuti mhinduro inogadzirisa nucleates nokukurumidza, iri nyore kudzora, midziyo iri nyore, uye inogona kubudisa. zvigadzirwa zvepamusoro. Asi zvakaoma kusefa uye nyore kuunganidza?
2. Hydrothermal nzira: Kurumidza uye simbisa iyo hydrolysis reaction yeion pasi pekushisa kwepamusoro uye mamiriro ekumanikidza, uye gadzira yakapararira nanocrystalline nuclei. Iyi nzira inogona kuwana nanometer poda ine yunifomu yekupararira uye yakamanikana particle size kugovera, asi inoda yakanyanya tembiricha uye yakakwirira yekumanikidza michina, inodhura uye isina kuchengetedzeka kushanda.?
3. gel nzira: Iyo yakakosha nzira yekugadzirira inorganic zvinhu, uye inoita basa rakakosha mune inorganic synthesis. Pakupisa kwakadzika, organometallic komisheni kana organic complexes inogona kuumba sol kuburikidza nepolymerization kana hydrolysis, uye kugadzira gel mune mamwe mamiriro. Kuwedzera kupisa kurapwa kunogona kugadzira ultrafine Rice noodles ine yakakura chaiyo nzvimbo uye kupararira kuri nani. Iyi nzira inogona kuitwa pasi pemamiriro akapfava, zvichiita kuti pave nehupfu ine nzvimbo yakakura yepamusoro uye nani dispersibility. Nekudaro, iyo nguva yekuita yakareba uye inotora mazuva akati wandei kuti ipedze, zvichiita kuti zviome kuzadzisa zvinodiwa zveindasitiri?
4. Solid phase method: high-temperature decomposition inoitwa kuburikidza nekomboni yakasimba kana yepakati Dry media reaction. Semuenzaniso, isingawanzo pasi nitrate uye oxalic acid inosanganiswa neiyo yakasimba chikamu bhora kugaya kuti iite yepakati yepasi isingawanzo Oxalate, iyo inozoora pakupisa kwepamusoro kuti iwane ultra-fine powder. Iyi nzira ine hunyanzvi hwekuita, midziyo yakapusa, uye kushanda kuri nyore, asi hupfu hunobuda hune morphology isina kurongeka uye kusafanana.?
Idzi nzira hadzisi dzakasiyana uye dzinogona kusashanda zvizere kumaindasitiri. Kune nzira dzakawanda dzekugadzirira, dzakadai se organic microemulsion nzira, alcoholysis, nezvimwewo?
3、 Kufambira mberi mukuvandudzwa kwemaindasitiri
Kugadzirwa kwemaindasitiri kazhinji hakutore nzira imwe chete, asi kunokwevera pane kusimba uye kunozadzisa kusasimba, uye kusanganisa nzira dzinoverengeka kuti uwane iyo yepamusoro chigadzirwa mhando, yakaderera mutengo, uye yakachengeteka uye inoshanda maitiro anodiwa pakushambadzira. Guangdong Huizhou Ruier Chemical Technology Co., Ltd. ichangobva kufambira mberi muindasitiri mukugadzira zvisingawanzo pasi nanomaterials. Mushure menzira dzakawanda dzekuongorora uye bvunzo dzisingaverengeki, nzira yakanyatsokodzera kugadzirwa kwemaindasitiri - microwave gel nzira yakawanikwa. Mukana wakakura weiyi tekinoroji ndeyekuti: yekutanga 10 zuva rekuita gel rakapfupikiswa kusvika zuva 1, kuitira kuti kugona kwekugadzira kuwedzere nekagumi, mutengo unodzikiswa zvakanyanya, uye mhando yechigadzirwa yakanaka, nzvimbo yepasi yakakura. , mushandisi wekuyedzwa kwemushandisi wakanaka, mutengo wakaderera ne30% pane wezvigadzirwa zveAmerica neJapan, izvo zviri kukwikwidza pasirese, Kuwana nhanho yepamusoro yepasirese.?
Munguva pfupi yapfuura, kuyedza kwemaindasitiri kwakaitwa pachishandiswa nzira yekunaya, kunyanya kushandisa ammonia mvura uye ammonia carbonate yekunaya, uye kushandisa organic zvinonyungudutsa mvura uye kurapwa pamusoro. Iyi nzira ine maitiro akareruka uye mutengo wakaderera, asi mhando yechigadzirwa haina kunaka, uye kuchine mamwe maagglomerations anoda kumwe kuvandudzwa nekuvandudzwa.?
China inyika huru mune zviwanikwa zvepasi zvisingawanzo. Kusimukira uye kushandiswa kweasingawanzo pasi nanomaterials kwakavhura nzira nyowani dzekushandisa zvine hungwaru zviwanikwa zvepasi, kuwedzera chiyero chezvisingawanzo kunyorera pasi, kwakasimudzira kugadzirwa kwezvinhu zvitsva zvinoshanda, kwakawedzera kutengeswa kunze kwenyika kwezvakanyanya kukosha zvigadzirwa, uye nekuvandudza kunze kwenyika. kuchinjana kuwana kugona. Izvi zvine zvakakosha zvinoshanda zvakakosha mukushandura mabhenefiti ezviwanikwa kuita zvakanakira hupfumi.
