Kusiyana nemidziyo yesimbi yechinyakare iyo inowanzova yakaoma uye inopfava, Zirconia ine simba rakawanda, inodzivirira kupera, uye inochinjika kupfuura dzimwe midziyo yesimbi yesimbi. Zirconia imidziyo yesimbi yakasimba kwazvo ine hunhu hwakanaka mukuoma, kusimba kwematombo, uye kuramba ngura; zvese izvi hazvina hunhu hwakajairika hwemidziyo yesimbi - kupfava kwakanyanya.
Kune mhando dzakasiyana dzeZirconia dziripo, idzo dzakajairika iYttria Partially Stabilized Zirconia (Y-PSZ) neMagnesia Partially Stabilized Zirconia (Mg-PSZ). Zvinhu izvi zvose zvinopa hunhu hwakanaka, zvisinei, nzvimbo yekushanda uye chikamu chejometri ndizvo zvinosarudza kuti ndeipi mhando yakakodzera kushandiswa kwakananga (zvimwe pamusoro peizvi pazasi). Kusagona kwayo kupararira kwematombo uye kuwedzera kupisa kwakanyanya kunoita kuti ive chinhu chakanaka chekubatanidza ceramics nesimbi dzakadai sesimbi. Nekuda kwehunhu hwayo hwakasiyana, dzimwe nguva inonzi "ceramic steel".
Zvivakwa zveZirconia Zvakajairika
● Kuwanda kwakanyanya - kusvika 6.1 g/cm^3
● Simba guru rekuchinjika uye kuomarara
● Kusimba kwakanyanya kwekukuvara - kunodzivirira kukuvadzwa
● Kupisa kwakanyanya kushandiswa
● Inodzivirira kupfeka
● Maitiro akanaka ekukakavadzana
● Chinodzivirira magetsi
● Kupisa kwakaderera - inenge 10% yeAlumina
● Kusagona ngura mumaacid nemaalkali
● Modulus yekusimba kwakafanana nesimbi
● Kuwanda kwekuwedzera kwekupisa kwakafanana nesimbi
Zvikumbiro zveZirconia
● Kugadzira waya/kudhirowa madhayi
● Mhete dzinodzivirira kupisa
● Mipini nemaekisi akakodzera munzvimbo dzakasakara zvakanyanya
● Machubhu ekugadzira vira
● Pfeka mapedhi ekudzivirira kupisa
● Machubhu ekudzivirira eThermocouple
● Maburi ekuputika kwejecha
● Zvinhu zvinoramba zvichichinja
