Alpha-al2o3 Aluminium oxide powder 99.99% Yakachena
Upfu hweAlpha-alumina (α-Al2O3), hunozivikanwa seupfu hwealuminium oxide, chinhu chinoshandiswa zvakasiyana-siyana uye chinoshandiswa zvakasiyana-siyana mumaindasitiri akadai seceramics, refractories, abrasives, catalysts, nezvimwewo. Heano mamwe marongero akajairika eupfu hwealpha-Al2O3
Kuumbwa kweMakemikari:
Aluminium oxide (Al2O3): Kazhinji 99% kana kupfuura.
Saizi yeChidimbu:
Kugoverwa kwehukuru hwezvikamu kunogona kusiyana zvichienderana nezvinodiwa zvekushandisa.
Avhareji yehukuru hwezvimedu inogona kubva pa-sub-micron kusvika kuma microns mashoma.
Upfu hwakatsetseka hunoita kuti pave nenzvimbo yakakwirira uye hunoita kuti pave nekuchinja kwezvinhu.
Ruvara:
Kazhinji ichena, ine mwero wakanyanya wekuchena.
Maumbirwo eKristaro:
Alpha-alumina (α-Al2O3) ine chimiro chekristaro chine hexagonal.
Nzvimbo Yakananga:
Kazhinji iri pakati pe2 kusvika 20 m2/g.
Upfu hwepamusoro hunowedzera mashandiro emuviri uye kufukidza kwenzvimbo.
Kuchena:
Upfu hwe alpha-Al2O3 hwakachena zvakanyanya hunowanikwa husina tsvina yakawanda.
Kuchena kwemuviri kunowanzova 99% kana kupfuura.
Kuwanda kwehuwandu:
Kuwanda kwehuwandu hweupfu hwealpha-Al2O3 kunogona kusiyana zvichienderana nemaitiro chaiwo ekugadzira kana giredhi.
Kazhinji inotangira pa 0.5 kusvika 1.2 g/cm3.
Kugadzikana kwekupisa:
Upfu hweAlpha-Al2O3 hunoratidza kugadzikana kwakanaka kwekupisa uye nzvimbo yekunyunguduka yakanyanya.
Pokunyunguduka: Inenge 2,072°C (3,762°F).
Kuoma:
Upfu hweAlpha-Al2O3 hunozivikanwa nekuoma kwahwo kwakanyanya.
Kuomarara kweMohs: Kunenge 9.
Kusashanda kweKemikari:
Upfu hweAlpha-Al2O3 hahuna chepfu uye hahusangani nemakemikoro mazhinji.
Inodzivirira maasidhi nemaalkali.
Zvakakosha kuziva kuti marongero chaiwo eupfu hwealpha-Al2O3 anogona kusiyana kubva kune vagadziri uye magiredhi chaiwo. Saka, zvinokurudzirwa kutarisa pepa redata rechigadzirwa kana kubvunza mutengesi kuti uwane ruzivo rwakadzama uye zvinodiwa chaizvo pakushandisa kwaunoda.
1. Zvinhu zvinopenya: phosphor ine ruvara rwegirini (rare earth trichromatic phosphors) inoshandiswa sechinhu chikuru chine phosphor refu, PDP, phosphor, LED;
2. Zviumbwa zvesimbi zvinopenya: zvinoshandiswa semachubhu e fluorescent erambi re sodium rinomanikidzwa zvakanyanya, hwindo rekurangarira rinoverengerwa chete nemagetsi;
3. Kristaro Imwe Chete: yekugadzira rubhi, safaya, yttrium aruminiyamu garnet;
4. Simba guru re alumina ceramic: se substrate inoshandiswa mukugadzira macircuit akabatanidzwa, maturusi ekucheka uye kuchena kwakanyanya;
5. Abrasive: gadzira abrasive yegirazi, simbi, semiconductor uye purasitiki;
6. Diaphragm: Kushandiswa kwekugadzira chifukidziro che lithium battery separator;
7. Zvimwe: sechipfeko chinoshanda, zvinosanganisa zvinhu zvinosimbisa ganda, zvinosimbisa ganda uye zvinotsigira zvinhu zvinosimbisa ganda, chipfeko chevacuum, zvinhu zvegirazi zvakakosha, zvinhu zvinosanganisa ganda, resin filler, bio-ceramics nezvimwewo.
