Dab tsi yog High-Purity Isostatic Graphite Crucible?

Lub High-Purity Isostatic Graphite Crucible yog lub thawv tsim ua los ntawm cov khoom siv graphite isotropic uas tsim los ntawm cov txheej txheem isostatic pressing. Piv nrog cov khoom siv graphite molded ib txwm muaj, isostatic graphite muaj:

● Cov qauv me me sib xws hauv txhua qhov kev taw qhia

● Qhov ceev thiab lub zog kho tshuab siab dua

● Kev ua tau zoo ntawm cov cua sov

● Kev tiv thaiv kev poob siab zoo heev

● Qhov porosity tsawg

● Cov ntsiab lus tsis muaj kuab paug ntau heev

Tom qab ntxuav, cov tshauv feem ntau tuaj yeem tswj tau qis dua 5 ppm, nrog rau qee cov ntaub ntawv semiconductor-qib ua tiav cov qib tsis huv hauv qab 3 ppm.

Cov yam ntxwv no ua rau High-Purity Isostatic Graphite Crucibles zoo tagnrho rau cov txheej txheem kub siab tshaj 2,000 ° C, qhov twg kev tswj hwm kev ua qias tuaj thiab kev sib xws ntawm thermal yog qhov tseem ceeb.

Lub Luag Haujlwm hauv Kev Tsim Khoom Semiconductor

Hauv Silicon Carbide (SiC) kev loj hlob ntawm cov siv lead ua los ntawm kev siv cov txheej txheem Physical Vapor Transport (PVT), cov graphite crucibles ua haujlwm ua ob qho tib si lub thawv ntim khoom siv thiab yog ib feem tseem ceeb ntawm lub tshuab thermal field. Ua haujlwm ntawm qhov kub feem ntau tshaj 2,200 ° C, lub crucible yuav tsum tswj qhov ruaj khov thaum txhawb nqa qhov kub thiab txias uas xav tau rau kev thauj mus los ntawm cov pa thiab kev tsim cov siv lead ua. Qhov huv thiab cov qauv isotropic ntawm graphite cuam tshuam ncaj qha rau kev koom ua ke ntawm cov khoom tsis huv, kev faib tawm thermal, kev loj hlob ntawm cov siv lead ua, thiab kev tsim cov khoom tsis zoo.

Lub luag haujlwm ntawm High-Purity Isostatic Graphite Crucibles nthuav dav tshaj qhov kev tsim khoom SiC mus rau hauv cov thev naus laus zis Gallium Nitride (GaN) crystal growth technologies. Txawm siv rau hauv HVPE, flux growth, lossis cov txheej txheem tsim khoom siv lead ua ntau, graphite crucibles muab ib puag ncig kub thiab ruaj khov uas txhawb nqa kev thauj khoom thiab kev tsim cov siv lead ua thaum txo qis kev pheej hmoo ntawm kev ua qias tuaj.

Hauv kev tsim cov khoom siv semiconductor epitaxial, suav nrog SiC epitaxy, AlN crystal growth, thiab advanced compound semiconductor processing, graphite crucibles pab txhawb rau thermal uniformity thiab cov txheej txheem rov ua dua. Lawv cov thermal conductivity zoo heev thiab kev tiv thaiv thermal shock ua rau kev ua haujlwm ruaj khov nyob rau hauv cov txheej txheem hnyav, txhawb kev tswj hwm qhov tseeb ntawm evaporation, sublimation, thiab deposition mechanisms.

Cov Khoom Siv Graphite Crucibles Uas Muaj Kev Phem Siab (High-Purity Isostatic Graphite Crucibles) kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv ceramic thiab cov hmoov semiconductor tiam thib peb. Thaum lub sijhawm sintering ntawm silicon carbide, aluminium nitride, boron nitride, thiab lwm yam ceramics ua tau zoo, lub crucible muab ib puag ncig ruaj khov thiab thermally uniform uas txhawb kev sib sau ua ke thaum txo qis kev ua qias tuaj. Cov kev txhim kho hauv cov khoom siv purity, thermal conductivity, thiab kev ua haujlwm mechanical yog qhov tseem ceeb rau cov ntawv thov xws li cov khoom siv semiconductor mus rau cov khoom siv hluav taws xob muaj zog siab.

Cov Qauv Kev Lag Luam thiab Kev Loj Hlob Yav Tom Ntej

Raws li cov khoom siv semiconductors dav dav txuas ntxiv hloov pauv kev lag luam hluav taws xob, qhov kev thov rau cov graphite crucibles siab heev tab tom nce ntxiv sai.

Cov Kev Cai Purity Siab Tshaj Plaws

Cov ntawv thov semiconductor yav tom ntej xav tau cov qib impurity qis dua 5 ppm thiab, qee zaum, yuav luag 1 ppm los txhawb cov qhov loj dua ntawm cov siv lead ua thiab cov qhov tsis zoo qis dua.

Cov Txheej Txheem Txheej Txheem

Cov txheej txheem pleev xim rau saum npoo av tau siv ntau dua rau cov graphite crucibles, suav nrog:

● Txheej Silicon Carbide (SiC)

● Txheej Tantalum Carbide (TaC)

● Txheej Txheem Pyrolytic Carbon (PyC)

Cov txheej txheem no ua kom zoo dua:

● Tiv thaiv kev xeb

● Kev ruaj khov ntawm cua sov

● Kev ua tau zoo tas mus li

● Kev ntxuav ntawm cov txheej txheem

● Cov Qauv Crucible Loj Dua

Kev lag luam ntawm:

● Cov wafer SiC 8-nti

● Cov khoom siv GaN loj dua

● Cov ntaub ntawv semiconductor fais fab siab heev

tab tom tsav tsheb txoj kev loj hlob ntawm cov graphite crucibles loj dua, ruaj khov dua uas muaj peev xwm tswj tau qhov kub thiab txias kom raug ntawm cov voj voog tsim khoom ntev.
