Kub-kev ntsuas hauv xeev tsuas tuaj yeem ua tau 30 feeb tom qab magnesium oxide refilling tau ua tiav sintering, txias rau chav tsev kub, thiab tau muab tso rau. Tag nrho cov txheej txheem, pib los ntawm sintering, feem ntau yuav siv sij hawm 4-6 teev.

Kev ntsuas hluav taws xob tiv thaiv rau kub- lub xeev kev ntsuas yuav tsum ua kom tiav nyob rau hauv 2 vib nas this ntawm lub hwj chim- tawm, nrog tus qauv ntawm Ntau dua lossis sib npaug li 200 MΩ, txhawm rau txheeb xyuas qhov kev ua haujlwm ruaj khov ntawm qhov kub thiab txias.
Kev ceev faj: Kev kuaj mob khaub thuas- xeev yuav tsum tau ua kom paub meej tias qhov kev ua tau zoo ntawm hluav taws xob ua tau raws li cov qauv ua ntej lub hwj chim; Thaum lub sijhawm ua haujlwm, saib xyuas qhov nkhaus tam sim no thiab kub nce kom ntseeg tau tias tsis muaj qhov hloov pauv txawv txav; Cov av noo nyob ib puag ncig yuav tsum tsawg dua lossis sib npaug li 30% kom tsis txhob muaj qhov cuam tshuam rau qhov kev nyeem ntawv.
Lub hwj chim rau yam tsis muaj qhov txias txaus lossis tsis dhau qhov txias - lub xeev qhov ntsuas yuav ua rau sab hauv micro- tawg tuaj yeem nthuav tawm, rwb thaiv tsev kom tawg, lossis lub casing tawg.
