Kub xovxwm sintering yog txheej txheem ntawm sintering ceramic nyob rau hauv ib tug tshwj xeeb siab. Nws tso cai rau cov cua kub ib txhij thiab kev sib zog ntawm cov ceramics los tsim cov ntaub ntawv nrog cov nplej zoo, cov txheeb ze siab, thiab cov khoom muaj zog.


Cov txheej txheem kub nias yog qhov tshwj xeeb zoo rau kev tsim cov khoom siv hluav taws xob siab kub siab (UHTCs), uas yog cov khoom siv uas tsis tshua muaj sinter rau siab ceev hauv cov txheej txheem sintering.


Tau ntau xyoo, cov kws tshawb fawb tau sim nrog ntau cov txheej txheem rau sinteringAlNthiab nce nws cov yam ntxwv.AlNnthuav tawm covalent bonding, yog li ntawd, txhawm rau kom tau txais tag nrho cov ntom ntom, nws yuav tsum tau sintered ntawm qhov kub siab tshaj 1800 ℃. Yog li ntawd, kub nias yog siv nyob rau hauv kev lag luam rau sinterAlNtsis muaj sintering additives.


Kub-xovxwm sintering yog ib qho kev ua haujlwm feem ntau los txhim kho lub zog ntawm AlN ceramics vim cov yam ntxwv tshwj xeeb. Ua ntej, lub zog-pab densification yog nqa tawm ua ke nrog cov txheej txheem kub-xovxwm sintering los pab tsim cov densified AlN ceramics. Sab nraud siab muab densification ib tug ntxiv thawb quab yuam nyob rau hauv sib piv rau pressureless sintering, txo qhov kub ntawm sintering los ntawm kwv yees li 50-150 ℃ thiab txwv lub foramtion ntawm loj nplej.


Kub-pressed aluminium nitride ceramic yog siv nyob rau hauv semiconductor kev lag luam uas yuav tsum tau muaj zog hluav taws xob tsis kam, siab flexural zog thiab zoo heev thermal conductivity.
