Alumina ceramics ke mofuta oa thepa ea ceramic e nang le Al2O3 e le thepa e ka sehloohong e tala le corundum (a-Al2O3) e le karolo ea mantlha ea kristale. Thempereichara ea sintering ea li-ceramics tsa alumina hangata e phahame ka lebaka la ntlha ea ho qhibiliha ea alumina e holimo ho 2050 C, e etsang hore tlhahiso ea lirafshoa tsa alumina e hloke ho sebelisa heater e phahameng ea mocheso kapa lisebelisoa tsa boleng bo holimo le li-refractories tsa boemo bo holimo joalo ka thepa ea sebōpi le ea sebōpi. , eo ho isa bohōleng bo itseng e lekanyetsang tlhahiso ea eona le tšebeliso e pharaletseng. Joale melemo ea eona ke efe?
Li-ceramics tsa alumina li na le melemo e mengata, joalo ka matla a phahameng a mochini, boima bo phahameng, tahlehelo e tlase ea dielectric ka maqhubu a phahameng, le ka lebaka la mohloli o pharalletseng oa lisebelisoa tse tala, theko e tlase haholo le theknoloji ea ts'ebetso e butsoitseng, e sebelisoa haholo masimong a lisebelisoa tsa elektroniki. lisebelisoa tsa motlakase, mechini, masela le sebaka sa sefofane. E boetse e thehile boemo ba eona bo phahameng tšimong ea lisebelisoa tsa ceramic. Ho tlalehoa hore lirafshoa tsa alumina ke lirafshoa tsa oxide tse sebelisoang ka ho fetisisa lefatšeng.
