Cenospherestuaj yeem siv hauvadvanced high-temperature ceramics los txhim kho lawv cov khoom thiab kev ua tau zoo. Nov yog ob peb txoj hauv kev uas cenospheres tuaj yeem muab tso rau hauv siab kub-kub ceramics:
1,Kev txhawb zog : Cenospheres tuaj yeem ua raws li cov khoom siv ntxiv hauv cov khoom siv ceramic. Lawv tuaj yeem muab ntxiv rau cov khoom siv ceramic, xws li alumina lossis silicon carbide, txhawm rau txhim kho lawv cov khoom siv kho tshuab, xws li lub zog, tawv, thiab tawg tsis kam. Cov cenospheres ua raws li lub teeb yuag thiab muaj zog ua kom muaj zog, cuam tshuam kev ntxhov siab thiab tiv thaiv kev tawg tawm hauv cov khoom siv ceramic.
2,Thermal rwb thaiv tsev : Cenospheres muaj thermal rwb thaiv tsev zoo heev vim lawv cov thermal conductivity tsawg thiab hollow qauv. Thaum muab tso rau hauv cov ntaub ntawv ceramic, lawv tuaj yeem txhim kho lawv cov peev txheej thermal rwb thaiv tsev. Qhov no yog tshwj xeeb tshaj yog zoo nyob rau hauv daim ntawv thov uas thermal stability thiab rwb thaiv tsev yog qhov tseem ceeb, xws li nyob rau hauv high-temperature furnace linings los yog thermal barrier coatings.
3.Tswj ceev : Cenospheres yog qhov hnyav thiab muaj qhov ntom ntom. Los ntawm kev ntxiv cenospheres rau cov txheej txheem ceramic, tag nrho qhov ntom ntawm cov khoom tshwm sim tuaj yeem raug txo. Qhov no yog qhov muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau txo qhov hnyav, xws li cov khoom siv hauv aerospace lossis cov khoom siv tsheb, tsis muaj kev cuam tshuam cov qauv kev ntseeg siab lossis kev ua haujlwm thermal ntawm cov ceramic.
4.Porosity Tswj : Cenospheres tuaj yeem pab tswj cov porosity ntawm cov ntaub ntawv ceramic. Nyob ntawm qhov xav tau qib porosity, cenospheres tuaj yeem siv los ua cov pore-forming agents. Cov cenospheres tuaj yeem muab faib rau hauv cov ceramic matrix thiab tom qab ntawd xaiv tshem tawm los ntawm cov txheej txheem tom ntej, tawm hauv qab tswj porosity hauv cov khoom siv ceramic. Qhov kev tswj porosity no tuaj yeem muaj txiaj ntsig zoo rau kev siv xws li kev pom, kev txhawb nqa catalyst, lossis thermal rwb thaiv tsev.
5.Dielectric Properties : Cenospheres muaj cov khoom siv hluav taws xob zoo. Thaum muab tso rau hauv cov ceramics siab heev, lawv tuaj yeem pab txhawb rau cov khoom siv dielectric. Qhov no ua rau cenosphere-txhim kho ceramics haum rau cov ntawv thov hauv hluav taws xob insulators, capacitors, lossis cov khoom siv hluav taws xob kub kub.
Txoj kev tshwj xeeb ntawm kev sib koom ua ke ntawm cenospheres rau hauv siab kub-kub ceramics nyob ntawm qhov xav tau thiab cov txheej txheem tsim khoom. Cenospheres tuaj yeem muab sib xyaw rau hauv cov hmoov ceramic lossis slurries ua ntej shaping thiab sintering, los yog lawv tuaj yeem qhia tau thaum lub sij hawm tsim cov khoom siv ceramics siv cov tswv yim xws li kub nias lossis infiltration. Nws yog ib qho tseem ceeb uas yuav tau xav txog kev sib raug zoo ntawm cov cenospheres thiab cov ceramic matrix, nrog rau qhov tsim nyog loj, kev faib tawm, thiab cov concentration ntawm cenospheres, uas tuaj yeem sib txawv nyob ntawm qhov kev thov tshwj xeeb thiab qhov xav tau ntawm cov khoom siv ceramic.
