I-Alpha-al2o3 I-aluminium oxide powder engu-99.99% Ubumsulwa
Impuphu ye-Alpha-alumina (α-Al2O3), eyaziwa kakhulu ngokuthi i-aluminium oxide powder, iyinto eguquguqukayo enezinhlobo eziningi zezicelo ezimbonini ezifana ne-ceramics, i-refractories, i-abrasives, i-catalysts, nokuningi. Nazi ezinye izincazelo ezijwayelekile zempuphu ye-alpha-Al2O3
Ukwakheka Kwamakhemikhali:
I-aluminium oxide (Al2O3): Ngokuvamile ingama-99% noma ngaphezulu.
Usayizi Wezinhlayiya:
Ukusatshalaliswa kosayizi wezinhlayiya kungahluka kuye ngezidingo ezithile zohlelo lokusebenza.
Usayizi wezinhlayiya ojwayelekile ungasukela ku-sub-micron kuya kuma-micron ambalwa.
Izimpushana ezincane ezinobukhulu bezinhlayiya zinikeza indawo ephezulu kanye nokusabela okusebenzayo.
Umbala:
Ngokuvamile kumhlophe, kuhlanzekile kakhulu.
Isakhiwo sekristalu:
I-Alpha-alumina (α-Al2O3) inesakhiwo sekristalu esinonxande.
Indawo Ekhethekile Yomphezulu:
Ngokuvamile kuphakathi kuka-2 kuya ku-20 m2/g.
Izimpushana zendawo ephezulu zinikeza ukusebenza okwengeziwe kanye nokumbozwa kwendawo.
Ubumsulwa:
Ama-powder e-alpha-Al2O3 ahlanzekile kakhulu avame ukutholakala ngokungcola okuncane.
Izinga lokuhlanzeka livame ukuba ngu-99% noma ngaphezulu.
Ubuningi:
Ubuningi bempuphu ye-alpha-Al2O3 bungahluka kuye ngenqubo ethile yokukhiqiza noma izinga.
Ngokuvamile isukela ku-0.5 kuya ku-1.2 g/cm3.
Ukuzinza Kokushisa:
Impuphu ye-Alpha-Al2O3 ibonisa ukuzinza okuhle kakhulu kokushisa kanye nendawo yokuncibilika ephezulu.
Indawo yokuncibilika: Cishe 2,072°C (3,762°F).
Ubulukhuni:
Impuphu ye-Alpha-Al2O3 yaziwa ngokuqina kwayo okuphezulu.
Ubulukhuni be-Mohs: Cishe u-9.
Ukungasebenzi Kwamakhemikhali:
Impuphu ye-Alpha-Al2O3 ayinawo amakhemikhali futhi ayisebenzi kumakhemikhali amaningi.
Ayimelani nama-acid nama-alkali.
Kubalulekile ukuqaphela ukuthi imininingwane eqondile yempuphu ye-alpha-Al2O3 ingahluka phakathi kwabakhiqizi kanye namazinga athile. Ngakho-ke, kungcono ukubheka ishidi ledatha lomkhiqizo noma uxhumane nomhlinzeki ukuthola ulwazi oluningiliziwe kanye nezidingo ezithile zesicelo sakho osihlosile.
1. Izinto ezikhanyayo: ama-phosphor e-trichromatic angavamile asetshenziswa njengezinto eziyinhloko zokusetshenziswa njenge-phosphor ende ekhanyayo, i-phosphor ye-PDP, i-phosphor ye-LED;
2.Izinto zobumba ezisobala: ezisetshenziswa njengamashubhu e-fluorescent esibani se-sodium esinomfutho ophezulu, iwindi lememori elifundekayo kuphela elihlelwa ngogesi;
3. Ikristalu Elilodwa: lokwenziwa kwerubi, isafire, i-yttrium aluminium garnet;
4. I-alumina ceramic enamandla aphezulu: njenge-substrate esetshenziswa ekwakhiweni kwamasekethe ahlanganisiwe, amathuluzi okusika kanye ne-crucible emsulwa kakhulu;
5. I-Abrasive: yenza i-abrasive yengilazi, insimbi, i-semiconductor kanye nepulasitiki;
6. I-Diaphragm: Isicelo sokwenziwa kwengubo yokuhlukanisa ibhethri le-lithium;
7. Okunye: njengesembozo esisebenzayo, ama-adsorbents, ama-catalyst kanye nezisekelo ze-catalyst, isembozo se-vacuum, izinto ezikhethekile zeglasi, izinto ezihlanganisiwe, i-resin filler, i-bio-ceramics njll.
