Sintering tom qab refilling yuav siv sij hawm 1-2 teev, nqa tawm nyob rau hauv ib tug inert cua ntawm 800-1000℃los xyuas kom meej txaus recrystallization ntawm magnesium oxide nplej, tsim ib tug ntom thiab ruaj khov insulating qauv.
Qhov tseem ceeb ntawm cov txheej txheem sintering:
|
Yam khoom |
Parameter |
|
Qhov kub thiab txias |
800-1000 degree |
|
Tuav lub sijhawm |
1-2 teev |
|
Huab cua |
Inert gases xws li nitrogen los tiv thaiv oxidation |
|
Txoj kev txias |
Ntuj cua txias rau hauv lub cub tawg kom tsis txhob thermal stress cracking |
Tom qab sintering, sealing kev kho mob thiab ntau yam kev xeem yuav tsum tau. Tag nrho kev xa rov qab- mus rau- cov txheej txheem rov ua lub Hoobkas feem ntau siv sijhawm 3-5 hnub ua haujlwm.
