Dielectric ceramics, yomwe imadziwikanso kuti dielectric ceramics, imatchulansozoumba za ceramiczomwe zimatha polarize pansi pa ntchito ya magetsi ndipo zimatha kukhazikitsa malo amagetsi m'thupi kwa nthawi yaitali.Makatani a dielectric ali ndi kukana kwamphamvu kwambiri, kukana kwamagetsi, kutsika kwa dielectric pang'ono, kutayika kwa dielectric Low, mphamvu zamakina apamwamba komanso kukhazikika kwamankhwala abwino, omwe amagwiritsidwa ntchito makamaka mu ma capacitor ndi zigawo za microwave.
Zida zamagetsi zamagetsi zimaphatikizapo zida za ceramic dielectric monga ferrodielectric ceramics, semiconductor dielectric ceramics, high-frequency dielectric ceramics ndi microwave dielectric ceramics.
Nano ceramic ceramics ndi zida zatsopano zogwirira ntchito zokhala ndi antibacterial, activation, adsorption, filtration, ndi ntchito zina zomwe zimagwiritsidwa ntchito poyeretsa mpweya komanso kukonza madzi.Ntchito ya Mineralization.
Piezoelectric ceramics amatanthawuza ferroelectric ceramics omwe ndi ma polycrystals opangidwa ndi sintering oxides (zirconia, lead oxide, titanium oxide, etc.) pa kutentha kwambiri komanso kulimba kwa gawo, ndipo amapatsidwa chithandizo cha DC high voltage polarization kuti akhale ndi piezoelectric effect.Ndizinthu zogwirira ntchito za ceramic zomwe zimatha kusintha mphamvu zamakina ndi mphamvu zamagetsi kuti zigwirizane.Chifukwa cha makina ake abwino komanso zinthu zokhazikika za piezoelectric, zoumba za piezoelectric ndizofunikira kwambiri, kutentha, magetsi, ndi zipangizo zogwiritsira ntchito kuwala.
Zomwe zimagwiritsidwa ntchito nthawi zambiri za piezoelectric zimaphatikizapo masensa, zoyatsira gasi, ma alarm, zida zomvera, zida zowunikira zamankhwala ndi mauthenga... Zomwe zimagwiritsidwa ntchito nthawi zonse za piezoelectric ndi PZT, ndipo zida zatsopano za ceramic za piezoelectric zimaphatikizapo kukhudzidwa kwambiri, zida za ceramic zokhazikika kwambiri za piezoelectric, electro strictive. zipangizo za ceramic, pyroelectric ceramic zipangizo, etc.
Ma ceramics owoneka bwino
Transparent functional ceramic zinthu ndi mawonekedwe owoneka bwino.Kuphatikiza pa kukhala ndi mikhalidwe yonse yoyambira yazambiri za ferroelectric ceramics, ilinso ndi ma electro-optical effect.Kupyolera mu ulamuliro wa zigawo zikuluzikulu, akhoza kusonyeza pakompyuta ankalamulira birefringence zotsatira ndi pakompyuta ankalamulira kuwala kubalalika.Zotsatira, kusokonezedwa kwapamadzi koyendetsedwa ndi magetsi, mphamvu yamagetsi, pyroelectric effect, photovoltaic effect, ndi chithunzi chokhwima ...
Zida za ceramic zowonekera zitha kupangidwa kukhala zida zogwiritsira ntchito ma electro-optical ndi electro-mechanical pawiri pazifukwa zosiyanasiyana: zosinthira zolumikizirana zowoneka bwino, zolumikizira kuwala, zodzipatula zowoneka bwino, zosungirako zowoneka bwino, zowonera, zowonera zenizeni zenizeni, ma optical fiber docking Micro-displacement. ma drive, masensa amphamvu kwambiri, ma driver owoneka, etc.
Ndi chitukuko chofulumira cha sayansi yakuthupi, zinthu zatsopano zosiyanasiyana ndi ntchito zatsopano za zida za ceramic zimadziwika nthawi zonse ndi anthu.Zida za ceramic zogwira ntchito zakhala zikugwiritsidwa ntchito popanga mphamvu, ukadaulo wa mlengalenga, ukadaulo wamagetsi, ukadaulo wozindikira, ukadaulo wa laser, ukadaulo wa optoelectronic, ukadaulo wa infrared., biotechnology, sayansi ya chilengedwe ndi magawo ena amagwiritsidwa ntchito kwambiri.Zida za ceramic zomwe zimagwira ntchito zikukulanso motsata magwiridwe antchito apamwamba, kudalirika kwakukulu, magwiridwe antchito ambiri, miniaturization, ndi kuphatikiza.
