Cov txheej txheem tsim khoom

1. Cov txheej txheem ntau lawm

Ua rau hauv Cordierite Ceramic Pieces los ntawm kev siv tshuab ceramic. Lub sintering ntau yog nqaim, qhov kub ntawm sintering tsuas yog ob peb degrees deb ntawm qhov decomposition kub ntawm cordierite, thiab nws yog ib qho nyuaj kom tau txais lub cev ntom ntom. Chlorite, magnesium carbonate, barium carbonate, zirconium silicate, zirconium dioxide, boron trioxide, spodumene, thiab lwm yam yog feem ntau siv los ua additives, uas tuaj yeem txo qhov kub thiab txias, nthuav dav sintering kub ntau, thiab txhim kho nws cov khoom dielectric. Nws tuaj yeem siv los ua coil bobbin, arc-resistant hluav taws xob insulating cov ntaub ntawv, cov khoom siv hauv cov khoom siv sib xyaw, thiab cov khoom siv rau cov khoom siv hluav taws xob thiab cov thermal insulating. Lub npe lus Askiv ntawm cordierite yog Cordierite, uas yog lub npe hu ua kev hwm ntawm Fabkis geologist PLA Coedier, thaum lub pov haum zoo cordierite yog hu ua Iolite lossis Dichroite hauv lus Askiv. Iolite yog muab los ntawm Greek thiab txhais tau tias "violet", uas yog lub cim xim ntawm lub pov haum zoo iolite. Cordierite muaj qhov pom tseeb pleochroism, thiab nws cov xim tuaj yeem pom muaj kev hloov pauv pom tseeb thaum pom los ntawm ntau lub ces kaum nrog qhov muag liab qab.
