Magnesia-stabilized zirconia (MSZ) e na le mamello e kholo ho khoholeho ea mobu le ho tšoha ha mocheso. Mekhahlelo e menyane ea tetragonal e hola ka har'a li-cubic phase ea li-zirconias tse thata tse kang magnesium-stabilized zirconia. Ha fracture e leka ho tsamaea ka har'a lintho tse bonahalang, li-precipitates tsena li fetoha ho tloha karolong ea tetragonal ea meta-stable ho ea karolong e tsitsitseng ea monoclinic. Ka lebaka leo, pula e hola, e etsa hore ntlha e robehileng e be butle, 'me ho be thata ho eketseha. Ka lebaka la phapang ea hore na thepa e tala e lokisitsoe joang, MSZ e ka ba lenaka la tlou kapa 'mala o mosehla oa lamunu. MSZ, e nang le 'mala oa lenaka la tlou, e hloekile ebile e na le litšobotsi tse itseng tsa boleng bo holimo. Mocheso o phahameng (220°C le ho feta) le maemong a mongobo o phahameng, MSZ e tsitsitse ho feta YTZP, mme YTZP hangata e theola boemo. Ntle le moo, MSZ e na le conductivity e tlase ea mocheso le CTE e ts'oanang le tšepe ea tšepe, e thibelang ho se lumellane ha mocheso lits'ebetsong tsa ceramic-to-metal.

Lisebelisoa
Magnesia-stabilized zirconia e ka sebelisoa ka li-valve, lipompo le li-gaskets hobane e na le ts'ebetso e ntle ea ho apara le ho thibela ho bola. Hape ke thepa e ratoang bakeng sa likarolo tsa petrochemical le chemical processing. Zirconia ceramics ke khetho e ntle bakeng sa likarolo tse ngata, ho kenyelletsa:
Li-ceramics tsa sebopeho

Sebakeng sa eona se botala, libisikiti, kapa libakeng tse teteaneng ka ho feletseng, MSZ e ka etsoa ka mochine. Ha e le ka mofuta o tala kapa oa li-biscuit, e ka 'na ea etsoa ka mokhoa o rarahaneng oa lijeometri ka mokhoa o bonolo. 'Mele oa zirconia o fokotseha ka hoo e ka bang 20% nakong ea ts'ebetso ea sintering, e leng ho hlokahalang ho tiisa thepa ka ho lekaneng. Ka lebaka la ho honyela hona, zirconia pre-sintering e ke ke ea etsoa ka mamello e kholo haholo. Thepa e sirelelitsoeng ka botlalo e tlameha ho etsoa ka mochini kapa ho tlotsitsoe ka lisebelisoa tsa daemane e le ho fumana mamello e matla haholo. Ka mokhoa ona oa ho etsa, thepa e siloa ka ho sebelisa sesebelisoa kapa lebili le kolobisitsoeng ka taemane ho fihlela sebopeho se hlokahalang se fumaneha. Sena e ka ba ts'ebetso e jang nako ebile e theko e boima ka lebaka la boima ba tlhaho le boima ba thepa.
