Aluminium oxide Ceramics

氧化铝陶瓷-Alumina Ceramic

Alumina ceramics ke mofuta oa alumina (Al2O3) e le thepa ea mantlha ea ceramic, hajoale ke e 'ngoe ea lirafshoa tse khethehileng tse atileng haholo, tse ka sebelisoang haholo indastering ea theknoloji e phahameng le ea maemo a holimo, joalo ka li-microelectronics, li-reactors tsa nyutlelie, aerospace, makenete. ho fehla matla a mokelikeli, lesapo la maiketsetso le manonyeletso a maiketsetso le likarolo tse ling, ka mohau le lerato la batho.

 

Lisebelisoa tsa aluminium tsa ceramic li na le melemo e latelang:

1, ho thatafala ha lirafshoa tsa alumina ho phahame haholo, ho hanyetsa ho apara hantle.

2, lirafshoa tsa alumina li na le khanyetso ea ho bola ha lik'hemik'hale le thepa ea khauta e qhibilihisitsoeng.

3, lisebelisoa tsa alumina ceramic li na le insulation e ntle haholo, tahlehelo e phahameng ea maqhubu e batla e le nyane empa e na le litšobotsi tse ntle tsa ho kenya maqhubu.

4, lisebelisoa tsa alumina ceramic li na le litšobotsi tsa ho hanyetsa mocheso, coefficient e nyane ea katoloso ea mocheso, matla a maholo a mochini le conductivity e ntle ea mocheso.

5, khanyetso ea ho roala ha li-ceramics tsa alumina e ntle, empa boima bo tšoana le ba corundum, 'me ho hanyetsa ho roala ha Mohs hardness level 9 ho bapisoa le li-alloys tse matla haholo.

6, li-ceramics tsa alumina li na le litšobotsi tsa ho se chese, mafome, ha ho bonolo ho senya, e leng lisebelisoa tse ling tsa manyolo le lisebelisoa tsa tšepe li ke ke tsa lumellana le ts'ebetso e babatsehang.
