1. Ntau yam khoom siv alumina ceramic siv hauv lub neej muaj qee qhov yuav tsum tau ua rau hardness, yog li qhov hardness yuav tsum tau kuaj xyuas thaum lees txais cov alumina ceramic tuav. Tsis tas li ntawd, cov thermal conductivity thiab hnav tsis kam ntawm alumina ceramic tuav yuav tsum tau kuaj xyuas. Vim tias ntau qhov chaw uas siv cov alumina ceramic bar yog ntub, qhov kev tiv thaiv corrosion ntawm alumina ceramic tuav kuj yuav tsum tau muab sau tseg.
2. Rau cov khoom siv alumina ceramic, qhov hluav taws kub yuav tsum tau kuaj xyuas, thiab cov qauv hluav taws kub ntawm alumina ceramic tuav yog qhov siab tshaj 1000 degree, uas yog qhov tseem ceeb heev. Tsis tas li ntawd, thaum lub alumina ceramic tuav nyob rau hauv lub xeev kub, cov kua qaub tsis kam ntawm lawv cov corrosion kuj yuav tsum tau txhim kho, uas kuj yog ib qho tseem ceeb ntawm alumina ceramic khoom. Ua tib zoo saib qhov no thaum kuaj xyuas.
3. Ntxiv rau cov ntsiab lus tsuas yog hais, qhov ceev ntawm alumina ceramic khoom feem ntau yog ib qho tseem ceeb rau kev ntsuas qhov zoo. Rau alumina ceramic tuav, qhov ceev yuav siab heev, thiab kev sib raug zoo lom neeg yuav tsum zoo. Cov ntsiab lus no xav tau kev saib xyuas. Tsis tas li ntawd, lub melting point ntawm alumina ceramic tuav yog siab heev, vim hais tias alumina ceramic khoom yuav tsum yog ib qho ntawm cov ntaub ntawv uas muaj hluav taws kub heev nyob rau hauv cov xwm.
