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.

I-titanate yePlatinum kunye nesisombululo sayo esiqinileyo i-semiconductorized yi-ceramic molding eqhelekileyo kunye ne-high-tempering sintering ukufumana izinto ze-thermistor ezineempawu ezintle. I-coefficient yayo yobushushu kunye ne-Curie point yeqondo lokushisa iyahluka ngokubunjwa kunye neemeko ze-sintering (ingakumbi ubushushu bokupholisa).
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 onokubakho 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.
