Aluminium Oxide Ceramics

氧化铝 -Alumina Ceramic

Ubukorikori bwa Alumina ni ubwoko bwa alumina (Al2O3) nk'ibikoresho nyamukuru by'ubutaka, kuri ubu ni bumwe mu bukorikori budasanzwe busanzwe, bushobora gukoreshwa cyane mu nganda z’ikoranabuhanga rikomeye kandi zigezweho, nka mikorobe, amashanyarazi, ingufu za kirimbuzi, icyogajuru, rukuruzi kubyara amashanyarazi, amagufwa yubukorikori hamwe nubukorikori hamwe nibindi bintu, kubwabantu nurukundo.

 

Alumina ceramic ibikoresho bifite ibyiza bikurikira:

1, ubukana bwa ceramics ya alumina ni ndende cyane, irwanya kwambara neza.

2, ceramics ya alumina ifite imiti irwanya ruswa hamwe na zahabu yashongeshejwe.

3, ibikoresho bya alumina ceramic bifite insulasiyo nziza, gutakaza inshuro nyinshi ni bito ariko byiza biranga insimburangingo.

4, ibikoresho bya alumina ceramic bifite ibiranga kurwanya ubushyuhe, coefficente ntoya yo kwagura ubushyuhe, imbaraga za mashini nini hamwe nubushyuhe bwiza bwumuriro.

5, kwihanganira kwambara kwa alumina ceramics nibyiza, ariko ubukana nubwa corundum, kandi kwihanganira kwambara kwa Mohs kurwego rwa 9 biragereranywa nubwa superhard alloys.

6, ceramics ya alumina ifite ibiranga ibidacanwa, ingese, ntibyoroshye kwangirika, nibindi bikoresho kama nibikoresho byuma ntibishobora guhura nibikorwa byiza.
