Alumina grinding balls have become a popular grinding medium in the pharmaceutical industry due to their ultra-high hardness, excellent wear resistance, chemical inertness, and high purity, making them ideal for micronizing active pharmaceutical ingredients, formulation preparation, and biopharmaceutical research and development.

Ceramic metallization yog cov txheej txheem ntawm kev tso cov hlau nplaum heev rau saum npoo ceramic. Qhov no yog ib kauj ruam tseem ceeb vim tias ceramics yog inherently unwettable rau solder. Cov txheej metallized ua rau lawv tuaj yeem ua tau, muab lub hauv paus tsim nyog rau kev sib txuas ntawm cov ceramic-rau-hlau muaj zog.

Ib txwm hlau-core printed circuit boards (MCPCBs) muaj cov thermal tsis kam vim qhov yuav tsum tau polymer rwb thaiv tsev txheej ntawm cov hlau thiab Circuit Court txheej, ua rau lawv tsis muaj peev xwm ua tau raws li qhov xav tau ntawm cov cua kub dissipation ntawm high-power thiab ultra-high-power LEDs. Nyob rau hauv sib piv, ceramic substrates muab rwb thaiv tsev thiab thermal conductivity, tshem tawm interfacial thermal kuj

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.
