Zvigadziko zveAlumina zveceramiczvinhu zveceramic zvinoshanda zvakanyanya zvinoumbwa nealuminium oxide. Zvinowanzogadzirwa kuburikidza nemaitiro ekupisa zvakanyanya. Zvichienderana nehuwandu hwealumina, zvinoiswa muzvikamu zve low-purity (75%-85% Al₂O₃), medium-purity (96% Al₂O₃), uye high-purity (≥99% Al₂O₃). Zvichiratidzwa ne microstructure yakakora uye makemikari akagadzikana, ma substrates aya anoratidza simba remakanika rakanaka, kuramba kupisa kwakanyanya, uye kudzivirira magetsi. Anoshandiswa zvakanyanya sezvinhu zvekutanga mumagetsi, masisitimu emagetsi, ndege, uye mamwe maindasitiri epamusoro.
Mabhenefiti eAlumina Ceramic Substrates:
Kudzivirira Kwemagetsi Kunoshamisa
Nekusimba kwakanyanya (>10¹⁴ Ω·cm) uye kusachinja-chinja kwe dielectric (8-10), alumina ceramics inonyatsoparadzanisa magetsi emagetsi, ichidzivirira kushomeka kwemagetsi munzvimbo dzine mafrequency akawanda kana kuti ma voltage akawanda.
Kufambisa Kwekupisa Kwakanyanya
Zvidimbu zvine 96% yealumina zvine simba rekupisa re24-28 W/(m·K), zvichiita kuti kupisa kubve muzvikamu zvemagetsi kuparadzirwe zvakanaka kudzivirira kupisa zvakanyanya uye kuwedzera hupenyu hwemuchina.
Simba Repamusoro reMichina
Simba rekuchinjika re300-400 MPa, pamwe chete nekuomarara kwakanyanya (Mohs hardness 9) uye kuramba kupfeka, zvinoita kuti igare kwenguva refu mumamiriro ekushanda akaomarara.
Kugadzikana Kwakasimba Kwemakemikari
Zvichiramba acids, alkalis, oxidation, uye hunyoro, alumina substrates dzinochengetedza kushanda kwakasimba kunyangwe pakupisa kwakanyanya (kusvika 1600°C) kana munzvimbo dzine ngura.
Kugadzira Nemazvo
Kugadzira nemazvo kunoita kuti pamusoro payo pave nekutsetseka kwe micron, zvichizadzisa zvinodiwa zvemashandisirwo akadai sekurongedza zvinhu zve semiconductor.
