Iyo yemuviri chimiro che scandium oxide inotaridzwa nekusimba kwayo kwekupisa, ichiratidza kunyungudika kwakanyanya kunyungudika kunowanzo kuwira mukati meiyo 2400 kusvika 2485 madhigirii celsius, chirevo chemasimba akasimba einteratomic mukati mecrystalline lattice. Iyo yekubikira kwayo inotonyanya kukwidziridzwa, ichiwedzera kusimbisa hunhu hwayo hwekuramba uye kugona kwayo kumirisana nemamiriro ekunze ekupisa pasina kuita shanduko inoparadza. Iine chaiyo giravhiti inosvika 3.86 magiramu pa cubic centimita, ine mwero density, chinhu chinopesvedzera huremu hwese mumashandisirwo apo kureruka kwezvinhu chinhu chakakosha dhizaini dhizaini. Uyezve, scandium oxide inoratidzira kusanyungudika mune aqueous media, hunhu hunobva kune yakasimba ionic bonding mukati mechimiro chayo, kunyangwe ichikurumidza kupera mukunyungudika mumamineral acids pakupisa, ichigadzira inoenderana scandium munyu, hunhu hwemakemikari hunoshandiswa mune dzakasiyana siyana dzekugadzira uye yekuchenesa maitiro. Kemikari,scandium oxideinoratidza amphoteric maitiro, kunyangwe kukosha kwayo kunonyanya kutaurwa kupfuura acidity yayo, ichiibvumira kuita nemhando dzine acidic kugadzira munyu. Sezvineiwo, inogona zvakare kutora mumhepo kabhoni dhaokisaidhi, kunyanya pamberi pehunyoro, zvichitungamira pakuumbwa kwepamusoro carbonates kana hydroxycarbonates, chiitiko chinoda kungwarira kuchengetedza kuchengetedza kuchena kwayo.
Kupfuura maitiro ayo anobatika, scandium oxide inoratidza inonakidza sutu ye optical uye zvemagetsi zvivakwa zviri kuwedzera kubatanidzwa muhunyanzvi hwepamusoro. Indekisi yaro yerefractive, yakakwira kusvika pa1.85 kusvika 1.96 zvichienderana newavelength uye density yezvinhu, inoita kuti ive yakakosha mukugadzirwa kwe optical coatings uye lenses, inosimudzira kushanda kwechiedza chekufambisa nekugadzirisa. Kuratidzira kwakakosha transmissivity kuyambuka uye pedyo-infrared zvikamu zve electromagnetic spectrum, inoshanda sechinhu chakakosha mumahwindo ekuona uye seyakajeka substrate yemafirimu matete mune optoelectronic zvishandiso. Uyezve, kana yaiswa zvine hungwaru nemaion epasi asingawanzo, scandium oxide inoratidzira photoluminescence, ichiburitsa mwenje weavelength chaiwo pamusoro pekunakidzwa, chivakwa chiri pakati pekushandiswa kwayo musimba rinoshanda nesimba rakasimba-nyika uye matekinoroji ekuratidzira. Mumamiriro ayo emukati, scandium oxide inoshanda seyemagetsi insulator, inoratidzwa nepamusoro resistivity, hunhu hwakakosha pakushandiswa kwayo sechinhu che dielectric muzvikamu zvemagetsi, kudzivirira kubuda kusingadiwe kwazvino. Yayo yakanyanya kukwirisa dielectric nguva dzose inoita kuti ive yakakodzera kushandiswa mumacapacitors, kufambisa kuchengetedza kwesimba mukati memagetsi maseketi.
Kuti unzwisise macroscopic maitiro e scandium oxide, kunzwisisa kweiyo yepasi peatomu dhizaini yakakosha. Iyo inopenya mu cubic Bixbyite chimiro, chimiro chakajairwa pakati peasingawanzo pasi sesquioxides, inoratidzwa nechiso-chepakati cubic kurongeka kwe oxide anions ine scandium cations inogara chaiyo octahedral nzvimbo, kunyangwe ine inherent anionic vacancies. Aya maumbirwo ezvimiro anoraira interatomic kureba uye bonding angles, pakupedzisira achipesvedzera kugadzikana kwezvinhu uye zvivakwa. Iyo yakarongedzerwa uye yakasimba ionic bonding mukati meiyi crystal lattice inobatsira zvakanyanya kune iyo yakanyanya kunyungudika nzvimbo uye makemikari inertness pasi pemamiriro mazhinji.
Ichipinda kupfuura hunhu hwayo hwakakosha, scandium oxide inoratidza huwandu hwepamusoro uye huri kusimukira zvivakwa zviri kukwezva kufarira kwakakosha mukutsvaga-kumucheto. Kumusoro kwaro kunoratidza chiitiko chinokonzeresa kune mamwe makemikari shanduko, uye kugona kwayo kushambadza akasiyana mamorekuru ari kuongororwa mu sensor tekinoroji. Ipo insulator yemagetsi, ine inoyerwa yekupisa conductivity, inogonesa kupisa kupisa, chinhu chakakosha mukukwira-simba remagetsi maapplication. Iyo yakaderera coefficient yekuwedzera kwekupisa inovimbisa kugadzikana kwedimensional pane dzakasiyana siyana tembiricha, hunhu hunodiwa muhuinjiniya hwechokwadi. Uyezve, kuoma kwayo kwakakosha uye kuomarara kwepakati nepakati kunobatsira pakusimba kwayo munzvimbo dzinodiwa dzemuchina.
Pakupedzisira, iyo yakasarudzika confluence ye scandium oxide yemuviri, makemikari, optical, zvemagetsi, uye zvemakanika zvivakwa zvinoraira zvakasiyana uye kuwedzera huwandu hwekushandisa. Kugadzikana kwayo kwekushisa uye kupenya kwemagetsi kunotsigira kushandiswa kwayo mukuvhenekera kwepamusoro-soro. Kugona kwayo kusimudzira simba uye weldability yealuminium alloys, kuburikidza nekunatswa kwezviyo, kwakakosha mune aerospace uye mota engineering. Iyo dielectric uye insulating zvivakwa zvinoshandiswa mumagetsi ceramics uye capacitors. Iyo refractive indekisi uye pachena inokwidziridzwa mune optical coatings. Iyo catalytic chiitiko chepamusoro payo inoongororwa mumakemikari synthesis, uye kugona kwayo adsorption kunoshandiswa muma sensor matekinoroji. Iyo yakarongedzerwa doping ye scandium oxide ine zvisingawanzo pasi zvinhu inogonesa kugadzirwa kweakasarudzika phosphors yekuvhenekesa kwepamusoro uye kuratidza maapplication. Sezvo tsvakiridzo ichienderera mberi nekuburitsa kuomarara kwezvivakwa zvayo uye nekuongorora nzira itsva dzekugadzira, mashandisirwo escandium oxide akagadzirira kuwedzera kuwedzera, kusimbisa basa rayo sechinhu chakakosha mukufambira mberi kwetekinoroji.
