Aluminium Nitride Ceramic Structure

Aluminium nitride, paub los ntawm nws cov tshuaj npe AlN lossis nitride ntawm txhuas (nitruro de aluminio, nitrure d'aluminium), yog cov khoom siv ceramic zoo heev. Feem ntau hu ua AIN ceramic, aluminium nitride ceramic, los yog tsuas yog AlN ceramic, nws yog lub npe hu rau nws cov thermal conductivity zoo heev, hluav taws xob rwb thaiv tsev siab, thiab cov khoom zoo heev. Nws nthuav tawm cov qauv hexagonal wurtzite siv lead ua, ua rau nws qhov tshwj xeeb ua ke ntawm lub cev thiab tshuaj lom neeg cov yam ntxwv, ua rau AlN cov ntaub ntawv muaj txiaj ntsig zoo.

1. High thermal conductivity

Aluminium nitride ceramics muaj thermal conductivity siab heev, nrog rau qhov theoretical tus nqi txog li 320W / m·K thiab tus nqi ntawm 170W / m·K txog 240 / m·K, uas yog ntau dua li cov tsoos alumina ceramics. Qhov no ua rau aluminium nitride ceramics yog cov khoom siv hluav taws xob zoo tshaj plaws, tsim nyog rau cov khoom siv hluav taws xob, LED teeb pom kev zoo, cov khoom siv laser thiab lwm yam kev lag luam, txhim kho kev ua haujlwm zoo thiab lub neej ntawm cov khoom siv.

2. Cov rwb thaiv tsev hluav taws xob zoo heev

Aluminium nitride ceramics muaj cov hluav taws xob zoo, tsis tshua muaj hluav taws xob tsis tu ncua, tsis tshua muaj hluav taws xob poob, thiab nyob ruaj khov ntawm qhov siab. Cov yam ntxwv no ua rau nws nyiam cov khoom siv hauv siab - zaus, siab - cov khoom siv hluav taws xob hluav taws xob, xws li siab - zaus Circuit Court substrates, lub hwj chim module ntim, thiab lwm yam.

3. Zoo thermal expansion txuam

Lub thermal expansion coefficient ntawm aluminium nitride ceramics yog hais txog 4.5 × 10^-6 / K, uas yog ze heev rau cov khoom siv semiconductor xws li silicon (Si) thiab gallium arsenide (GaAs). Qhov no ua rau aluminium nitride ceramics yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob semiconductor, pab txo cov kev ntxhov siab thermal thiab txhim kho kev ntseeg tau thiab ruaj khov ntawm cov khoom siv.

Aluminium nitride ceramics yog siv dav hauv cov khoom siv hluav taws xob thiab siab -kub kev lag luam. Cov khoom tseem ceeb suav nrog AlN wafers, AlN substrates (aluminium nitride substrates), thiab AlN nplooj ntawv (aluminium nitride sheet, AlN phaj). Hauv microelectronics, lawv ua cov dab dej kub (ALN lub dab da dej), polished substrate (AIN polished substrate, ALN polished substrate), thiab insulating txheej rau integrated circuits thiab LED pob vim lawv thermal conductivity. High thermal conductivity substrate (AIN siab thermal conductivity substrate, ALN siab thermal conductivity substrate) yog qhov tseem ceeb rau lub hwj chim hluav taws xob thiab siab - fais fab semiconductor modules.

Cov khoom siv dav siv hauv kev tswj xyuas thermal xws li AlN rhaub (txhuas nitride ceramic heaters), aluminium nitride rhaub phaj, thiab aluminium nitride thermal discs. Nws cov tshuaj ruaj khov ua rau nws zoo tagnrho rau kev siv cov crucibles (AlN crucible), raj, thiab daim hlau rau tuav cov hlau molten. Aluminium nitride structural Cheebtsam thiab qhov chaw muaj nyob rau hauv aerospace, automotive sensors, thiab raws li cov khoom tiv thaiv.

Tsis tas li ntawd, AlN yog siv rau hauv cov ntawv tshwj xeeb xws li microporous ceramic suction khob rau precision tuav, acoustic yoj li, thiab microwave Cheebtsam. Lub peev xwm los tsim cov khoom siv txhuas nitride kev cai-xws li kev cai substrates, crucibles, raj, phaj, thiab qhov chaw- tso cai rau cov kev daws teeb meem thoob plaws kev lag luam siab heev. Ua txhuas nitride manufacturers thiab lwm tus neeg, xws li Maruwa, muab cov high - cov ntaub ntawv ua tau zoo, nrog rau cov nqi txhuas nitride qhia txog nws cov khoom siab heev thiab raug precision.
