Cov Khoom Siv Ceramic Tshiab (1)

Cov khoom siv ceramic tsim los ntawm kev siv cov haujlwm tshwj xeeb ntawm cov ceramics ntawm lub cev muaj zog xws li suab, lub teeb, hluav taws xob, hlau nplaum, thiab cua sov hu ua haujlwm ceramics.Muaj ntau hom kev ua haujlwm ceramics nrog kev siv sib txawv.Piv txwv li, cov khoom siv hluav taws xob xws li conductive ceramics, semiconductor ceramics, dielectric ceramics, insulating ceramics tuaj yeem ua raws li qhov sib txawv ntawm cov khoom hluav taws xob ntawm ceramics, uas yog siv los ua cov capacitors, resistors, high-temperature thiab high-frequency devices nyob rau hauv cov khoom siv hluav taws xob. hluav taws xob kev lag luam, transformers thiab lwm yam khoom siv hluav taws xob.

Semiconductor ceramics

Semiconductor ceramics hais txog poly crystalline ceramic cov ntaub ntawv tsim los ntawm ceramic technology, nrog semiconductor yam ntxwv thiab hluav taws xob conductivity ntawm txog 10-6 ~ 105S / m.Cov conductivity ntawm semiconductor ceramics hloov pauv loj vim yog kev hloov pauv ntawm cov xwm txheej sab nraud (kub, lub teeb, hluav taws xob, huab cua thiab qhov kub thiab txias, thiab lwm yam), yog li qhov hloov pauv ntawm lub cev nyob rau hauv ib puag ncig sab nraud tuaj yeem hloov mus rau hauv cov teeb liab hluav taws xob los ua cov khoom rhiab rau ntau yam. lub hom phiaj.

Cov khoom siv hlau nplaum ceramic

Sib nqus ceramics tseem hu ua ferries.Cov ntaub ntawv no xa mus rau cov khoom sib nqus oxide sib nqus uas muaj hlau ions, oxygen ions thiab lwm yam hlau ions, thiab muaj qee qhov sib nqus oxides uas tsis muaj hlau.Ferries feem ntau yog semiconductors, thiab lawv qhov kev tiv thaiv yog ntau dua li cov khoom siv hlau hlau sib nqus, thiab lawv muaj qhov zoo ntawm qhov poob tam sim no me me.Nyob rau hauv lub teb ntawm high zaus thiab microwave technology, xws li radar technology, kev sib txuas lus technology, chaw technology, hluav taws xob computer thiab lwm yam, nws tau dav siv.

High kub superconducting ceramics

Superconducting oxide ceramics nrog kub tseem ceeb dua.Nws cov superconducting tseem ceeb kub yog siab dua cov kua helium kub cheeb tsam, thiab cov qauv siv lead ua yog hloov zuj zus los ntawm Dnepropetrovsk qauv.High kub superconducting ceramics muaj siab dua superconducting kub dua hlau.Txij li thaum muaj kev vam meej hauv kev tshawb fawb ntawm superconducting ceramics hauv xyoo 1980s, kev tshawb fawb thiab kev siv cov khoom siv kub kub superconducting ceramics tau nyiam ntau yam.Tam sim no, daim ntawv thov ntawm cov khoom siv kub kub superconducting yog tsim los ntawm cov ntawv thov tam sim no, cov ntawv siv hluav taws xob, thiab cov diagnetism.

Insulating ceramics

Kuj tseem hu ua ntaus ntawv ceramics.Nws yog siv los ua ntau yam insulators, insulating structural qhov chaw, band keyboards thiab capacitor txhawb brackets, hluav taws xob tivthaiv ntim shells, integrated circuit substrates thiab ntim shells, thiab lwm yam. Insulating ceramics muaj cov yam ntxwv ntawm siab ntim resistivity, tsis tshua muaj dielectric coefficient, tsis tshua muaj qhov poob, siab dielectric zog, corrosion kuj thiab zoo mechanical zog.
