Alumina ceramics imhando yealumina (Al2O3) sechinhu chikuru checeramic material, parizvino iri imwe yeanonyanya kukosha makeramics, inogona kushandiswa zvakanyanya mumaindasitiri epamusoro-soro uye ekucheka-kumucheto, senge microelectronics, nuclear reactors, aerospace, magnetic. kugadzirwa kwemagetsi emvura, bhonzo rekugadzira uye majoini ekugadzira uye zvimwe zvinhu, nekufarirwa nevanhu nerudo.
Alumina ceramic zvinhu zvine zvinotevera zvakanakira:
1, kuoma kwealuminium ceramics kwakakwira zvakanyanya, kunaka kupfeka kuramba.
2, alumina ceramics ine kemikari corrosion kuramba uye yakanyungudutswa yegoridhe zvivakwa.
3, alumina ceramic zvinhu zvine yakanakisa insulation, yakakwira frequency kurasikirwa idiki asi yakanaka yakakwirira frequency insulation maitiro.
4, alumina ceramic zvinhu zvine hunhu hwekupisa kupisa, diki coefficient yekuwedzera kupisa, hombe yemagetsi simba uye yakanaka yekupisa conductivity.
5, kusagadzika kwealumina ceramics kwakanaka, asi kuomarara kwakafanana nekorundum, uye kusagadzika kwekuoma kweMohs level 9 kunofananidzwa neiyo superhard alloys.
6, alumina ceramics ine hunhu hwekusapisa, ngura, isiri nyore kukuvadza, izvo zviri zvimwe organic zvinhu uye simbi zvinhu hazvigone kuenderana nekuita kwakanakisa.
