Cov ntaub ntawv ceramic tau siv rau ntau yam kev siv, suav nrog hauv kev lag luam hluav taws xob ua cov khoom siv hluav taws xob, insulators, thiab resistors. Ceramics muaj cov khoom hluav taws xob tshwj xeeb uas sib txawv ntawm lwm cov ntaub ntawv xws li hlau thiab polymers. Hauv tsab xov xwm no, peb yuav tshuaj xyuas qhov sib txawv ntawm cov khoom siv hluav taws xob ceramic, insulators, thiab resistors.
Ceramic Electrical Conductors
Ceramics tuaj yeem ua hluav taws xob, txawm tias tsawg dua li cov hlau. Qee cov ntaub ntawv ceramic, xws li ruthenium oxide thiab lanthanum strontium cobalt ferrites, tau pom tias muaj hluav taws xob ua tau zoo thaum ua tiav txoj hauv kev. Ceramic hluav taws xob conductors yog siv nyob rau hauv ntau yam kev siv, nrog rau cov thermocouples, cua kub ntsiab, thiab roj sensors.
Ceramic hluav taws xob conductors tseem paub txog lawv qhov kub thiab txias, ua rau lawv zoo tagnrho rau kev siv hauv cov ntawv thov uas xav tau qhov kub thiab txias. Piv txwv li, qee cov ceramics, xws li alumina thiab silicon nitride, tuaj yeem tiv taus kub txog li 2000 degree.
Ceramic Hluav Taws Xob Insulators
Hluav taws xob insulating ceramics yog siv rau hauv cov ntawv thov uas qhov kev khiav ntawm hluav taws xob los ntawm cov khoom yuav tsum tau tiv thaiv. Cov ceramics no muaj kev tiv thaiv siab, txhais tau tias lawv ua hluav taws xob tsis zoo. Hauv kev siv hluav taws xob, ceramic insulators yog siv los txhawb thiab cais cov khoom siv hluav taws xob los ntawm ib leeg. Lawv kuj tuaj yeem siv los insulate high voltage cables thiab ua cov khoom siv hluav taws xob insulating txheej.
Ceramic insulators muaj qhov kub thiab txias ua haujlwm zoo, tso cai rau lawv siv rau hauv cov ntawv thov kub kub qhov twg lwm cov ntaub ntawv yuav ua tsis tiav. Cov ntawv thov no suav nrog cov khoom siv insulating rau nuclear reactors thiab aerospace applications.
Ceramic Resistor
Ceramic resistors yog ib hom hluav taws xob tiv thaiv uas tiv thaiv qhov ntws ntawm tam sim no los ntawm ib lub voj voog. Lawv tau siv ntau yam khoom siv hluav taws xob, suav nrog khoos phis tawj, TV, thiab khoom siv kho mob. Ceramic resistors tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, nrog rau axial lead resistors, nto mount resistors, thiab nti resistors.
Ceramic resistors yog tsim los ntawm kev tso ib txheej ntawm cov khoom tiv thaiv mus rau ib qho ceramic substrate. Cov khoom siv tiv thaiv feem ntau yog hlau oxide, xws li tin oxide lossis ruthenium oxide. Lub thickness ntawm cov txheej resistive txiav txim siab qhov tsis kam ntawm tus resistor.
Ceramic resistors muaj ntau qhov zoo dua li lwm hom resistors, nrog rau lawv qhov kev ruaj ntseg ntawm qhov kub thiab txias thiab lawv lub peev xwm los tswj cov hluav taws xob ntau dua thiab cov tam sim no. Ceramic resistors kuj tseem txhim khu kev qha thiab muaj lub neej ntev.
Hauv cov ntsiab lus, ceramics tau dav siv hauv kev lag luam hluav taws xob vim lawv cov khoom hluav taws xob tshwj xeeb. Ceramic hluav taws xob conductors, insulators, thiab resistors yog siv nyob rau hauv ntau yam kev siv, los ntawm roj sensors thiab cua kub ntsiab rau high-voltage cables thiab electronics. Cov ntaub ntawv ceramic muaj ntau qhov zoo dua lwm cov ntaub ntawv, suav nrog lawv cov kev kub siab, kev ruaj khov, thiab kev ntseeg tau. Raws li kev siv thev naus laus zis, ceramics yuav tsis muaj kev ntseeg txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev lag luam hluav taws xob.
