Mas siv cov txheej txheem ntawm cov txheej txheem ntawm cov insulator ntawm cov dielectric capacitors, thiab nws cov qauv yooj yim yog qhov sib tshooj ntawm cov ceramics thiab cov hluav taws xob sab hauv. Cov khoom siv ceramic ntawm ntau hom. Txij li thaum tsis muaj mob xav txog cov khoom siv hluav taws xob yog taug txhuas-dawb, siab dielectric coefficient ntawm PB (hmoov txhuas) kom tawm ntawm thaj teb ntawm cov ceramic capacitors, tam sim no feem ntau siv TiO2 (titanium dioxide), BaTiO3, CaZrO3, (calcium zirconate). Kev loj me me, muaj peev xwm loj, zoo thaum tshav kub kub tsis kam, haum rau cov huab hwm coj ntau lawm thiab tus nqi qis piv rau lwm lub zog.
