Cov tsev no ua rau AlN plooj (porcelain) zoo tagnrho rau cov ntawv thov uas ob qho tib si kev saib xyuas thermal thiab hluav taws xob seclusion ib txhij hu rau, xws li hauv kev tiv thaiv nkag bipolar transistors (IGBTs) thiab laser diode chaw.
Cov txheej txheem tsim khoom thiab cov khoom nyuaj
Ua high-purity, high-density aluminium nitride ceramics hu rau qhov tseeb hmoov synthesis thiab sintering cov tswv yim. Cov txheej txheem muaj xws li carbothermal txo ntawm alumina hauv nitrogen ambience thiab ncaj nitridation ntawm hlau aluminium. Ua kom tiav tag nrho cov densification yam tsis muaj kev loj hlob ntau dhau, sintering pab xws li yttria, calcium oxide, los yog erbium oxide nquag ntxiv. Txawm li cas los xij, oxygen contamination nyob twj ywm ib qho kev sib tw loj, raws li nws cov ntaub ntawv insulating aluminium oxynitride theem uas deteriorate thermal kev ua tau zoo. Kev nce qib tam sim no hauv kev kub nias, Lub teeb plasma sintering, thiab additive-free processing yog pab kom dhau cov kev txwv no, coj txoj hauv kev rau ultra-high-conductivity AlN substratums.
Kev siv hauv Electronics thiab Semiconductor Ntim
Ib qho kev pom zoo tshaj plaws siv AlN porcelains yog nyob rau hauv cov khoom siv hluav taws xob, tshwj xeeb tshaj yog rau cov cuab yeej siv hluav taws xob thiab cov khoom siv siab. Nyob rau hauv superhigh zaus (RF) modules, optoelectronics, thiab lub teeb-emitting diodes (LEDs), AlN substratums ua haujlwm raws li ob qho tib si kev txhawb nqa thiab txhim khu kev qha sov so. Lawv kuj tau dav siv hauv cov khoom siv hluav taws xob semiconductor, qhov twg lawv cov thermal shock tsis kam thiab pureness kom ntseeg tau cov txheej txheem hauv kev puas tsuaj plasma cua. Nrog rau kev nce tsheb hluav taws xob thiab 5G cov chaw sib txuas lus, thov rau AlN-raws li cov dab dej sov, cov phiaj xwm microwave, thiab sensor vaj tse tseem loj hlob sai thoob plaws ntiaj teb kev lag luam.
Lub luag haujlwm tseem ceeb hauv Quantum Technologies thiab Deep UV Optics
