Zirconia (YSZ) Molamu o silang mecha ea litaba
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.
Lithupa tsa Yiho YSZ
Joalo ka morekisi ea ka sehloohong oa thepa ea ceramic e etselitsoeng esale pele lebopong le ka bochabela la USA, QS Advanced Materials e sebetsa haufi-ufi le baetsi ba lisebelisoa tsa ceramic sintering le machining ho fana ka lihlahisoa tsa zirconia tse tsitsitseng ka theko e ntle haholo.Re tsoela pele ho fana ka li-crucibles tsa zirconia le lisebelisoa tse ling tsa motheo.Ka li-stocks tse felileng, le bokhoni bo phahameng ba tlhahiso, melemo ea nako le litšenyehelo e fanoa.
Likopo tsa likarolo tsa Yttria Stabilized Zirconia (YSZ,YTZP).
• E sebelisoa bakeng sa ho sila lisebelisoa tsa letsopa, lisebelisoa tsa makenete le lisampole tsa tlhaho
• Likarolo tse ling tsa mochini oa ho beleha le tse ling
• Likarolo tse khethehileng tsa pompo

Sephutheloana
Joalo ka thepa ea ceramic, thepa ea Zirconia e ntse e fokola, leha YSZ e fetoha habonolo.Lithupa tsa rona tsa zirconia hangata li ts'oaroa ka mekotleng ea polasetiki ka vacuum, 'me li sireletsa ka foam e boima.
