Berylllicium oxide (boo) ceramicsMuaj nuj nqis heev hauv cov khoom siv khoom ua ntej rau lawv cov kev ua kom sov sov condal thiab hluav taws xob tsis kam hluav taws xob. Beo, cov khoom siv sib xyaw ua ke, ua ke cov neeg kho tshuab zog ntawm ceramics muaj zog ntawm cov khoom cua sov dissipation, ua rau nws zoo meej rau kev siv cov khoom siv siab. Nws cov yam ntxwv txawv los ntawm nws cov qauv crystalline, uas qhia txog ob qho tib si resilience hauv kev hnyav thiab tshwj xeeb insulating muaj peev xwm.

Tus mosCov ntawv thov luv luv ntawm cov kev lag luam qib high tech, suav nrog cov khoom siv hluav taws xob siab, suav nrog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob uas muaj sia nyob thaum khaws cia ua haujlwm. Qhov sib xyaw ua haujlwm ntawm qhov kub thiab txias tsis muaj kev cuam tshuam, ua ke nrog nws cov kev siv hluav taws xob zoo, suav nrog kev siv hluav taws xob thiab cov tshuab tswj hluav taws xob.

Cov ntawv no feem ntau yog tham txog qhov zoo ntawm kev sivBeo daim hlauraws li terminal resistors.

Kev tawm tsam cov yaum nqus muaj hluav taws xob ntau thiab dissipate nws li cua sov.Tus mos'S irreplaceable nta qia feem ntau ntawm nws cov lus zoo tshaj plaws.

Qhov Zoo:

• Tsis tshua muaj cua sov condal: Qhov no yog qhov tseem ceeb tshaj plaws.Tus mosMuaj lub thermal conductivity ntawm 200-300 w / (m k), uas yog sib npaug rau feem ntau cov hlau thiab ntau tshaj kaum zaus ntawm Alumina. Qhov no ua rau kub kub sai khiav tawm ntawm lub resistor, uas tiv thaiv overheating overheating thiab ua tsis tiav.

• Txaus siab-kub lub zog thiab ruaj khov: tswj cov duab thiab kev ua tau zoo txawm nyob ntawm huab kub heev.

• Cov hluav taws xob hluav taws xob hluav taws xob: ua cov tshuaj ceramic, nws ua tau zoo tiv thaiv hluav taws xob los ntawm ntws ntawm lub resistor ntawm lub teeb resistor thiab lub hauv paus mounting.

• Coeffal expansion sib npaug rau silicon steel hlau: qhov kev txhim kho txhim khu kev qha thiab siv cov pob khaus khaus) los tsim cov tshuaj hermetic, txo qis kev phom sij vim yog thermal cycling.

Cov ntawv thov tseem ceeb rauBoo phajRau kev txiav tiv thaiv:

• Bo Ceramic PhajKev tawm tsam cov neeg tsim nyog feem ntau ua haujlwm hauv cov xwm txheej uas yuav tsum tau ua haujlwm zoo heev.

• RF thiab microwave loads yog siv los ua kev txiav tawm mus rau dissipate slammus lub zog hauv high-hwj chim amplifiers, cov astubsators, thiab cov cuab yeej sim.

• High-fais fab mem tes nqa khoom siv tau los tswj kev tsheb loj-zog pulse hauv radars, kev sib txuas lus hauv paus, thiab lwm yam khoom siv.

• Aerospace thiab defense electronics: siv rau hauv cov ntawv thov uas xav tau cov khoom siv siab siab muaj txiaj ntsig zoo, thiab lub zog siv hluav taws xob.
