I-PTC ibhekisela kwi-thermistor phenomenon okanye izinto eziphathekayo ngokunyuka okubukhali ekuchaseni kunye ne-coefficient yokushisa efanelekileyo kwiqondo lokushisa elithile, elinokusetyenziswa ngokukodwa njengenzwa yokushisa eqhubekayo.Izinto eziphathekayo ngumzimba we-sintered kunye ne-BaTiO3, i-SrTiO3 okanye i-PbTiO3 njengenxalenye ephambili, apho inani elincinci le-oxides ezifana ne-Nb, Ta, Bi, Sb, y, La kunye nezinye i-oxides zongezwa ukulawula i-valence ye-athomu ukuyenza. isemiconducting.Le semiconducting barium titanate kunye nezinye izinto zidla ngokubizwa ngokuba semiconducting (bulk) porcelain;ngelo xesha, i-oxides ye-manganese, isinyithi, ithusi, i-chromium kunye nezinye izongezo zongezwa ukunyusa i-coefficient yokushisa yokumelana okulungileyo.

Iikristale ze-Barium titanate ziyinxalenye yesakhiwo se-perovskite.Yimathiriyeli ye-ferroelectric, kunye ne-barium titanate ecocekileyo yimathiriyeli yokugquma.Emva kokongezwa kwezinto ezinqabileyo zomhlaba kwi-barium titanate kunye nonyango olufanelekileyo lobushushu, ukuxhathisa kunyuka ngokukhawuleza ngemiyalelo emininzi yobukhulu obujikeleze ubushushu beCurie, okukhokelela kwimpembelelo ye-PTC, ehambelana ne-ferroelectricity ye-barium titanate crystals kunye nezinto eziphathekayo. ubushushu beCurie.iinguqu zesigaba esikufutshane.Iiseramics ze-Barium titanate semiconductor zizinto ze-polycrystalline ezinobuchwephesha phakathi kweenkozo.Xa i-ceramic ye-semiconductor ifikelela kwiqondo lokushisa elithile okanye i-voltage, umda wengqolowa uyatshintsha, okukhokelela kutshintsho olubukhali ekuchaseni.
Impembelelo ye-PTC yeekeramics ze-barium titanate semiconductor ivela kwimida yeenkozo (imida yeenkozo).Ukuqhuba ii-electron, ujongano phakathi kwamasuntswana lusebenza njengesithintelo esinokubakho.Xa iqondo lokushisa liphantsi, ngenxa yesenzo sentsimi yombane kwi-titanate ye-barium, ii-electron ziyakwazi ukudlula ngokulula umqobo onokuthi ubekho, ngoko ixabiso lokumelana lincinci.Xa iqondo lobushushu liphakanyisiwe kufutshane neqondo lobushushu leCurie (oko kukuthi iqondo lobushushu elibalulekileyo), indawo yombane yangaphakathi iyatshatyalaliswa, engenakunceda ekuqhubeni ii-electron ukuwela umqobo onokubakho.Oku kulingana nokunyuka komqobo onokwenzeka kunye nokunyuka ngokukhawuleza kokuchasana, okubangelwa umphumo we-PTC.Imifuziselo ebonakalayo yempembelelo ye-PTC ye-barium titanate semiconductor ceramics iquka imodeli yokuthintela umphezulu we-Haiwang, imodeli yesithuba se-barium kunye nemodeli yesithintelo esiphezulu sikaDaniels et al.Benze ingcaciso efanelekileyo yesiphumo se-PTC kwimiba eyahlukeneyo.
