Piezoelectric seramiiki na-arụ ọrụ seramiiki ihe-piezoelectric mmetụta nke nwere ike tọghata n'ibu ike na eletriki ike.Na mgbakwunye na piezoelectricity, ceramics piezoelectric nwekwara ihe dielectric na elasticity.N'ime ọha mmadụ nke oge a, ihe piezoelectric, dị ka ihe na-arụ ọrụ maka ntụgharị electromechanical, na-arụ ọrụ dị mkpa na mpaghara nkà na ụzụ dị elu.

Ferroelectric ceramics bụ ụdị ceramics piezoelectric nke njirimara ya bụ:
(1) Enwere polarization na-akpaghị aka n'ụdị ọnọdụ okpomọkụ.Mgbe ọ dị elu karịa okpomọkụ Curie, polarization na-apụtaghị ìhè na-apụ n'anya na usoro ferroelectric na-agbanwe n'ime oge paraelectric;

Barium titanate bụ ihe ngwakọta ferroelectric nke nwere nnukwu dielectric mgbe niile na ọnwụ dielectric dị ala.Ọ bụ otu n'ime ihe ndị a na-ejikarị eme ihe na seramiiki eletrọnịkị ma mara ya dị ka "ogidi nke ụlọ ọrụ seramiiki eletrọnịkị".

BatIO3ceramics bụ nyocha na mmepe nke ihe seramiiki piezoelectric na-enweghị ndu tozuru oke nwere nnukwu dielectric mgbe niile, nnukwu ọnụọgụ electromechanical na-ejikọ ọnụ na piezoelectric mgbe niile, ihe nrụzi nke ọkara na obere mfu dielectric.

Dị ka a ferroelectric ihe onwunwe, barium titanate (BaTiO3) na-ọtụtụ-eji na muti-layer seramiiki capacitors, sonar, infrared radieshon nchọpụta, ọka ókè seramiiki capacitors, nti okpomọkụ ọnụọgụ ọnụọgụ kwes ceramics, wdg The sara mbara ngwa atụmanya mara dị ka ogidi nke electronic ceramik.Site na mmepe nke obere, dị arọ, nke a pụrụ ịdabere na ya na nke dị nro na ngwa eletriki na ihe ndị dị na ya, ọchịchọ maka ultra-fine barium titanate ntụ ntụ na-aghọwanye ngwa ngwa.
