Vim li cas semiconducting ceramics tig dub tom qab raug kub?

Xwm ntawm Semiconductor Ceramics
Semiconductor ceramics yog amorphous oxide cov ntaub ntawv uas muaj feem ntau ntawm silicon oxides thiab txhuas oxides. Cov yam ntxwv los ntawm siab -kub tsis kam, corrosion resistance, thiab siab mechanical zog, lawv yog cov ntaub ntawv tseem ceeb uas siv dav hauv kev lag luam semiconductor.

 

Ua rau siab -Tub kub Blackening hauv Semiconductor Ceramics
Txawm hais tias lawv tsis kam mus rau qhov kub thiab txias, cov khoom siv hluav taws xob semiconductor tuaj yeem ua rau blackening nyob rau hauv qee qhov siab - kub. Muaj ntau yam ua rau qhov tshwm sim no; Ntau qhov laj thawj muaj peev xwm tau teev tseg hauv qab no:

Muaj cov sulfur compounds los yog lwm yam tshuaj nyob rau hauv vapor los yog roj: cov tshuaj no reacts nrog cov ceramic nto los ua ib tug sulfide deposit txheej, ua rau saum npoo tig dub.

Oxide depletion thiab kev hloov ntawm cov qauv: Thaum kub kub, cov pa oxygen thiab silicon yuav khiav tawm ntawm cov iav siv lead ua lattice, tsim cov qauv hollow oxide. Kev tsim cov voids no tuaj yeem ua rau blackening.

Kev siv vuam ntau dhau thiab ua haujlwm kub: Thaum lub sij hawm tsim khoom, qhov kub thiab txias heev thaum lub sij hawm vuam los yog kev ua tiav tuaj yeem ua rau nto tawg thiab blackening.

Kub gradients ntau dhau: Thaum lub sij hawm sintering txheej txheem, ntxhab kub gradients kuj yuav ua rau cov ceramic nto dub.

 

Cov txheej txheem los tiv thaiv siab -Tub kub Blackening
Txhawm rau tiv thaiv semiconductor ceramics los ntawm blackening ntawm qhov kub thiab txias, cov kev ntsuas hauv qab no tuaj yeem ua:

Tswj lub atmospheric ib puag ncig kom txo qhov nkag ntawm cov pa phem rau hauv sintering chamber.

Tswj kev ua thiab vuam kub kom tsis txhob muaj qhov cuam tshuam ntawm cov cua sov ntau dhau ntawm cov ceramics.

Tswj qhov kub thiab txias gradients kom ntseeg tau tias cov ceramics tsis raug rau cov thermal sib txawv thaum sintering.

Xaiv lub siab- cov ntaub ntawv ceramic zoo los tiv thaiv blackening los ntawm cov khoom tsis xws luag.

Blackening nyob rau hauv semiconductor ceramics ntawm qhov kub thiab txias compromises lawv stability thiab kev pab cuam lub neej rau qee yam. Los ntawm kev nkag siab txog qhov ua rau blackening, xaiv siab - cov ntaub ntawv zoo, thiab kev tswj xyuas kev tshawb fawb xws li kev ua haujlwm kub thiab huab cua, cov tuam txhab tuaj yeem tiv thaiv qhov tshwm sim no thiab txhim kho kev ruaj ntseg thiab ntev ntawm cov khoom semiconductor.
