Alumina yog ib lub npe nquag rau txhuas oxide (Al2O3). Nws yog cov khoom siv hluav taws xob ruaj khov nrog kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob thiab hluav taws xob. Nws yog tsim rau ntau yam kev lag luam siv.

Boron nitride yog cov khoom siv hluav taws xob zoo nkauj uas tuaj hauv cov hmoov thiab cov khoom siv. Boron nitride yog cov khoom tshwj xeeb tiag tiag vim nws cov khoom tshwj xeeb, uas suav nrog lub peev xwm kub kub, tshwj xeeb thermal conductivity, yooj yim ntawm machining, lubricity, tsis tshua muaj dielectric tas li, thiab txhim kho dielectric zog.

Aluminium nitride yog cov khoom siv tau zoo hauv ntau yam kev lag luam vim nws cov khoom siv tshuaj thiab lub cev.Txawm li cas los xij, hauv kev tsim khoom, aluminium nitride feem ntau yog cais ua ob hom raws li cov txheej txheem sintering: pressureless sintered aluminium nitride thiab kub-pressed aluminium nitride. Cov yam ntxwv thiab kev siv ntawm ob pawg no txawv heev.

Boron carbide yog ib qho ntawm cov khoom siv ruaj khov thiab ruaj khov tshaj plaws muaj nyob rau hauv ib puag ncig niaj hnub no, qhov kev ua tau zoo, kev ua tau zoo, thiab kev ua neej nyob yog qhov tseem ceeb. Nws yog qhov paub zoo rau nws qhov zoo tshaj plaws thermal stability, tshuaj inertness, thiab nqi-zoo, thiab nws tau ua pov thawj tias nws yog ib qho khoom muaj nqis hauv ntau qhov kev lag luam, suav nrog kev tsim khoom thiab kev tiv thaiv.

Hauv tsev neeg Kovar, 4J29 yog tus qauv thiab cov khoom pom zoo rau brazing high-alumina ceramics, muab qhov sib npaug ntawm kev ua tau zoo, tus nqi, thiab kev cia siab. 4J33/34 yog kev txhim kho kev ua haujlwm rau cov ntawv thov tshwj xeeb uas xav tau kev ua haujlwm siab dua lossis cov yam ntxwv tsis sib xws. Lub brazing ntawm Kovar nrog alumina ceramics, uas yog txhawb los ntawm lawv cov therma

Boron nitride hmoov muaj qhov zoo tshaj plaws xws li thermal conductivity, rwb thaiv tsev, lubrication, kub-resistant, thiab tshuaj stability, ua rau nws ib tug saj zawg zog cov ntaub ntawv rau kev soj ntsuam nrog ntau yam teeb meem nyob rau hauv cov xwm txheej heev ua hauj lwm nyob rau hauv niaj hnub kev lag luam.

Active hlau brazing yog lub hauv paus txoj hauv kev tsim cov khoom siv hluav taws xob-rau-hlau junctions, nrog helium huab hwm coj spectrometer xau nrhiav kom tau raws li tus qauv kub rau kev lees paub lawv cov hermeticity. Kev sib xyaw ua ke ntawm ob lub thev naus laus zis no lav qhov kev cia siab ntev ntawm cov khoom siv welded hauv cov xwm txheej hnyav.

TiB2-BN-AlN composite conductive ceramic evaporation nkoj yog dav siv nyob rau hauv cov hlau evaporation kev lag luam vim cov txiaj ntsig ntawm cov khoom sib xyaw, uas sib txuas cov ntsiab lus siab melting, siab tshuaj stability, siab hardness, zoo conductivity, thiab zoo resistivity kub coefficient ntawm TiB2, hluav taws xob rwb thaiv tsev, molten hlau corrosion kuj, zoo heev thermal shoc.

Piv nrog rau cov khoom siv hauv huab cua los yog siab-sintered alumina pob, cov khoom tsim los siv cov txheej txheem HIP sawv cev rau qhov zoo leap.

Macor iav ceramic coj ua ke qhov yooj yim yas, qhov yooj yim ntawm kev ua kom zoo li hlau, thiab qhov ua tau zoo ntawm kev ua haujlwm siab ceramic. Nws yog iav-cerubic hybrid nrog cov cim tshwj xeeb los ntawm ob cov tsev neeg khoom siv. Macor yog ib qho hluav taws xob zoo thiab ua kom sov sov, nrog kev ua tau zoo nyob rau hauv kev kub kub, nqus tsev, thiab cov mob corrosive.
