99.99% Cov khoom siv ceramic toughened nano-alumina
Siv tau rau cov khoom siv ceramics, cov khoom siv ceramics, cov khoom siv ceramics pob tshab, thiab cov tshuab textile.
1. Vim yog qhov superplasticity ntawm nano-alumina hmoov, nws daws qhov tsis txaus ntawm qhov ntau ntawm daim ntawv thov txwv los ntawm qhov kub qis brittleness. Ntawm lawv, nano-aluminum oxy-carbide (SiC) nanocomposites yog qhov tseem ceeb tshaj plaws, thiab lawv lub zog flexural yog los ntawm Ib-theem alumina ceramics nce ntawm 300-400 MPa mus rau 1 GPa, thiab qhov tawg toughness ntawm cov khoom nce ntau dua 40%.
2. Kev ruaj khov ntawm thermal: Qhov ntxiv ntawm nano-alumina rau hauv cov ceramic substrate tsis yog tsuas yog txhim kho qhov kev ua tau zoo ntawm cov substrate, tab sis kuj txhim kho qhov kev ruaj khov ntawm cov khoom siv alumina substrate, thiab qhov kev ruaj khov ntawm thermal tau txhim kho los ntawm 2-3 zaug.
3. Qhov Ceev: Hauv cov txheej txheem ntawm cov hmoov extrusion molding, nano-α-Al2O3 hmoov tuaj yeem sau rau hauv cov qhov ntawm micron alumina hmoov, uas txo qhov loj me ntawm cov qhov; lub siab molding nce ntxiv, thiab tus lej ntawm cov qhov tuaj yeem txo qis, yog li txhim kho Qhov ceev ntawm cov khoom siv ceramic txhim kho qhov ceev thiab cov khoom siv kho tshuab ntawm alumina ceramics tom qab sintering.
4. Txo qhov kub ntawm sintering: qhov ntxiv ntawm nano-a-Al2O3 txhawb nqa kev ua haujlwm sintering thiab pab txo qhov kub ntawm sintering. Thaum qhov kub ntawm sintering yog 1450 ° C, lub zog flexural thiab qhov tawg toughness ncav cuag qhov siab tshaj plaws.
5. Kev ntxiv me me ntawm nano-a-Al2O3 tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov khoom siv. Lub alumina ceramic raug sintered ntawm 1450 ° C. Thaum qhov ntxiv yog 10%, lub zog flexural yog 415 mPa thiab qhov tawg toughness yog 4.1 MPa·m^1. /2.
