Zirconia (YSZ) Molamu o silang mecha ea litaba

Tlhaloso e Khutšoanyane:

Yttria stabilized zirconia(YTZP) ke sesebelisoa sa ceramic se tsoetseng pele se silafetseng mme ke mofuta o atileng haholo oa zirconia ceramic e tsitsitseng.Sebopeho se tloaelehileng sa Yttria Stabilized Zirconia ke 94.7% ZrO2 + 5.2% Y2O3 (phesente ea boima) kapa 97 ZrO2 + 3% Y2O3 (persente ea mol)

Li-tag tsa Sehlahisoa

Ha ho bapisoa le melamu ea alumina Yttria stabilized zirconia (YSZ YTZP) e ne e ka mamella mocheso o phahameng le ho feta.Zirconia e boetse e na le kutu e ntle le ho apara ho hanyetsa.E le thepa e hanyetsang haholo, mocheso o sebetsang oa lithupa tsa zirconia o ka ba holimo ho 1900C 'me oa tsitsa ho lik'hemik'hale tse ngata tse senyang hape.Li-crucible tsa Zirconia li boetse li fana ka ts'ebetso e tlase haholo ea mocheso le motlakase, ho etsa hore e be se loketseng bakeng sa lits'ebetso, e hloka insulating ea motlakase le ea mocheso.

Leha ho le joalo, ho fapana le boron nitride, molamu oa Zirconia ha o khothalletsoe hore o sebelisoe e le thepa e tala bakeng sa mosebetsi o eketsehileng oa machining, ka lebaka la boima bo phahameng le ho apara ho hanyetsa.
