Zirconia ke thepa e nang le matla a phahameng a mochine le ho robeha ho thata ka mocheso oa kamore. Zirconia ea rona (ZrO2) e kenyelelitsoe ka 3mol% Y2O3 zirconia e tsitsitseng e tsitsitseng (PSZ). Hobane bophara ba karoloana ea thepa ea PSZ e nyane, e ka sebetsoa ka nepo e phahameng, mme ts'ebeliso ea eona likarolong tse nepahetseng tsa machining joalo ka hlobo e ntse e hola. Ntle le moo, e ka sebelisoa bakeng sa lisebelisoa tsa indasteri, likarolo tsa sehokelo sa optical le lisebelisoa tse silakanyang. The high fracture toughness of PSZ e ka sebelisoa ho etsa liliba tse khethehileng, hape e sebelisoa haholo ka lithipa tsa ceramic tsa malapeng, slicer le likarolo tse ling.
Zirconia (ZrO2) Ke sebelisa haholo
Lisebelisoa tsa hlobo le hlobo (liforomo tse fapa-fapaneng, mokhoa o nepahetseng oa ho beha maemo, ho kenya letsoho); Likarolo tsa Mill (classifier, leloala la phallo ea moea, leloala la lifaha); Sesebelisoa sa indasteri (seha sa indasteri, mochini oa slitter, moqolo oa khatiso o bataletseng); Likarolo tsa sehokelo sa Optical (ring ea ho tiisa, sleeve, sebopeho sa V-groove); Selemo se khethehileng (coil spring, plate spring); Lihlahisoa tsa bareki (screwdriver tse nyane tse insulated, thipa ea ceramic, slicer).
