Alumina, kana Aluminium Oxide, inogona kugadzirwa mumhando yekuchena.Magiredhi akajairika anoshandiswa kune zvemazuva ano maindasitiri maapplication ari 99.5% kusvika 99.9% ane zvinowedzerwa zvakagadzirirwa kusimudzira zvivakwa.Yakasiyana-siyana nzira dzekugadzira ceramic dzinogona kuiswa kusanganisira machining kana mambure maumbirwo ekugadzira kugadzira akasiyana siyana saizi uye maumbirwo echikamu.
Al2O3 ceramics ine zvinotevera zvakanakira:
1. Kuomarara kwepamusoro (MOHS kuomarara ndeye 9) uye kunaka kupfeka kusagadzikana.
2. Simba rakanaka remagetsi.Iyo yekukotama simba inogona kusvika ku300 ~ 500MPa.
3. Yakanakisa kupisa kusagadzikana.Iyo inoramba ichishanda tembiricha inogona kusvika ku1000 ℃.
4. High resistivity uye yakanaka magetsi ekudzivirira zvinhu.Kunyanya ine yakanakisa tembiricha yekudzivirira (Kamuri-tembiricha resistivity is 1015Ω•cm) uye voltage breakdown kuramba (insulation simba 15kV/mm).
5. Kugadzikana kwakanaka kwemakemikari.Iyo haina kuita ne sulfuric acid, hydrochloric acid, nitric acid uye hydrofluoric acid.
6. High tembiricha ngura kuramba.Inogona kuramba zviri nani kukukurwa kwesimbi dzakanyungudutswa seBe, Sr, Ni, Al, V, Ta, Mn, Fe uye Co.
Naizvozvo, alumina ceramics anoshandiswa zvakanyanya muminda yemazuva ano maindasitiri.Inonyanya kushandiswa muindasitiri yekugadzira semiconductor, indasitiri yemagetsi, indasitiri yemuchina, yakanyanya tembiricha nharaunda, indasitiri yemakemikari, indasitiri yemwenje, machira uye mamwe minda.
Alumina chinhu checeramic chinoshandiswa zvakanyanya mune zvinotevera maapplication:
✔ magetsi insulators, corrosion-resistance zvikamu zvegasi lasers, zvesemiconductor kugadzirisa michina (senge chuck, end effector, chisimbiso mhete)
✔ magetsi ekudzivirira emagetsi machubhu.
✔ zvikamu zvezvimiro zveakakwira-vacuum uye cryogenic midziyo, nyukireya radiation zvishandiso, zvishandiso zvinoshandiswa pakupisa kwepamusoro.
✔ corrosion-resistance components, piston yemapombi, mavharuvhu uye dosing system, sampling mavharuvhu eropa.
✔ thermocouple tubes, magetsi insulators, kukuya midhiya, tambo madhairekitori.
