Isingeniso somkhiqizo
I-Boehmite, eyaziwa nangokuthi i-monohydrate alumina, iyi-hydroxide oxide ye-aluminium enefomula yamakhemikhali - i-AlOOH. Kungumkhiqizo omaphakathi wokuphelelwa amanzi kwe-aluminium hydroxide (ATH) ngaphansi kwezimo ezithile kanye nesandulela esibalulekile sokwakheka-kwe-alumina yezinga lokushisa eliphezulu ( - Al ₂ O3) ngokubala.

Izici Zomkhiqizo
Ifakwe ngendawo ethile ephezulu (imvamisa ifika ku-100-300 m²/g noma ngaphezulu kwalokho). Lokhu kunikeza inani elikhulu lezindawo ezisebenzayo ezingaphezulu, ezibalulekile ekuguquleni indawo kanye nokusebenzisana kobuso. Iphinde ifakwe nomsebenzi ongaphezulu. Ingaphezulu licebile ngamaqembu e-hydroxyl (- OH), okwenza kube lula ukuguqulwa kwendawo (njenge-silanization), okuyenza ihlakazeke kahle ezinhlelweni ze-organic noma kuhlanganiswe nama-polymer. Inezici ezinhle kakhulu zemishini. Umphumela wokugcwalisa we-nanoparticles ungathuthukisa kakhulu amandla, ukuqina, nobulukhuni bezinto eziyinhlanganisela. Inokuziphatha okushisayo okuyingqayizivele. Izici zokubola ezishisayo ze-boehmite cishe zingu-450-500℃, iyi-halogen-free flame retardant esebenzayo. Iphinde ibe nokusimama okuhle kwamakhemikhali, ukumelana nokugqwala, ukwahlukanisa, okungeyona ubuthi futhi ayinabungozi.
Isicelo somkhiqizo
Isetshenziswa njengento ewumgogodla yokuhlanganisa ulwelwesi lwe-ceramic camera (CCS), ulwelwesi lwe-boehmite lubola futhi lumunce ukushisa emazingeni okushisa aphezulu, futhi luguqule lube ungqimba lwe-alumina olunezimbotshana, olungathuthukisa kakhulu ukuzinza okushisayo kwesihlukanisi (ukuvimbela ukuncipha kokushisa), kuvimbele izifunda ezimfishane zokuthintwa kwe-electrode okuhle nokubi, futhi kuthuthukise kakhulu ukuphepha kwebhethri. Ingasetshenziswa-kumapulasitiki obunjiniyela aphezulu (afana ne-PA, i-PBT), irabha ekhethekile, ama-coatings angashi, nama-electrolyte aqinile. Ngenxa yomphumela wayo we-nano, inomphumela ongemuhle we-flame retardant kune-boehmite evamile, enokwengezwa okuncane kanye nomthelela omncane kuzakhiwo zemishini zezinto. Ibuye isetshenziswe kuma-catalysts kanye nezisekelo ze-catalyst, indawo enkulu ethize ivumela izingxenye ezihlakazekile ezisebenzayo zezinsimbi eziyigugu (njenge-Pt, i-Pd), okuholela kuma-catalysts asebenzayo futhi azinzile. Iyisandulela{5}yekhwalithi ephezulu yokulungiselela i-nano alumina ( - Al2 O3, - Al2 O3). I-nano alumina etholwe ngemva kokubala ingasetshenziswa ezinhlobonhlobo zezinkambu, njengokupholisha okunembayo, izitsha zobumba ezithuthukisiwe, izitsha zobumba ezibonisa ngale, njll.
