Chii chinonzi Aluminium Oxide inoshandiswa?
Alumina (Al2O3)inoshanda seyakagadziridzwa yemhando yakafara yezvigadzirwa zveceramic uye semumiriri anoshanda mukugadzirisa makemikari, anosanganisira adsorbents, catalysts, microelectronics, makemikari, aerospace indasitiri, uye imwe nzvimbo yepamusoro-soro.Iwo epamusoro maitiro alumina anogona kupa anoita kuti ive yakanakira kushandiswa mune akawanda maapplication.Zvimwe zvezvinonyanya kushandiswa kunze kwekugadzirwa kwealuminium zvakanyorwa pazasi.Fillers.Kuve yakanyatso makemikari inert uye chena, aluminium oxide inofarirwa kuzadza mapurasitiki.Girazi.Many magadzirirwo egirazi ane aluminum oxide sechinhu.Catalysis Aluminium oxide inokonzeresa maitiro akasiyana anobatsira mumaindasitiri.Kuchenesa gasi.Aluminium oxide inoshandiswa zvakanyanya kubvisa mvura kubva kune gasi hova.Abrasive.Aluminium oxide inoshandiswa pakuoma kwayo uye simba.Paint.Aluminium oxide flakes inoshandiswa mupende yekuratidzira yekushongedza mhedzisiro.Composite fiber.Aluminium oxide yakashandiswa mune zvishoma zvekuedza uye zvekutengesa fiber zvinhu zvepamusoro-kuita maapplication (semuenzaniso, Fiber FP, Nextel 610, Nextel 720).Zvombo zvemuviri. Zvimwe nhumbi dzokurwa nadzo dzinoshandisa mahwendefa ealuminium ceramic, kazhinji pamwe chete nearamid kana UHMWPE inotsigirwa kuti ibudirire pakurwisa kutyisidzira kwepfuti.Kudzivirirwa kweabrasion.Aluminium oxide inogona kukura seyakaputira paaluminium neanodizing kana neplasma electrolytic oxidation.Kuiswa kwemagetsi.Aluminium oxide insulator yemagetsi inoshandiswa se substrate (silicon on sapphire) yemasekete akabatanidzwa asiwo senzira inovharira kugadzirwa kwemidziyo ye superconducting yakadai senge single electron transistors uye superconducting quantum interference devices (SQUIDs).
Aluminium oxide, ichiva dielectric ine yakakura bhendi gap, inoshandiswa sechinhu chinodzivirira chinodzivirira muma capacitors.Mukuvhenekera, translucent aluminium oxide inoshandiswa mune mamwe mwenje wesodium vapor.Aluminium oxide inoshandiswawo mukugadzirira kuturika kwekumisikidza mune compact fluorescent marambi.Mumakemikari marabhoritari, aruminiyamu oxide isvikiro rekromatografia, inowanikwa mubasic (pH 9.5), acidic (pH 4.5 kana iri mumvura) uye maumbirwo asina kwaakarerekera.Hutano uye mishonga yekurapa inosanganisira iyo sechinhu mukutsiviwa kwehudyu uye mapiritsi ekudzivirira kubata pamuviri.Iyo inoshandiswa se scintillator uye dosimeter yekudzivirira nemwaranzi uye kurapwa mashandisirwo eiyo optically inokurudzirwa luminescence zvimiro.Insulation yehuni dzekudziya kwepamusoro inowanzogadzirwa kubva kualuminium oxide.Zvidimbu zvidiki zvealuminium oxide zvinowanzo shandiswa semachipisi ari kufashaira mumakemikari.Inoshandiswawo kugadzira spark plug insulators.Ichishandisa plasma yekupfapfaidza maitiro uye yakasanganiswa netitania, inonamirwa pamusoro pemabhureki emamwe marimu ebhasikoro kupa abrasion uye kusapfeka.Mazhinji maziso eceramic pamatanda ekuredza zvindori zvedenderedzwa zvakagadzirwa kubva kualuminium oxide.Muchimiro chayo chehupfu (chena) chakanakisa, chinonzi Diamantine, aruminiyamu oxide inoshandiswa seabrasive yepamusoro yekunatsa mukugadzira wachi nekugadzira wachi.Aluminium oxide inoshandiswawo mukuputira ma stanchions mumuchinjiko wemota uye indasitiri yemabhasikoro egomo.Ichi chipfeko chinosanganiswa ne molybdenum disulfate kuti ipe nguva refu yekuzora pamusoro.
