Izakhiwo zeZirconia Ceramics

I-Zirconia ceramics (ZrO2), enezinga eliphakeme lokuncibilika, ukuqina okuphezulu, ukumelana okuhle kakhulu kokugqoka, njenge-insulator ekushiseni okujwayelekile, futhi ekushiseni okuphezulu kunezindawo zokuqhuba. I-Pure ZrO2 imhlophe, iphuzi noma impunga uma iqukethe ukungcola, futhi ngokuvamile iqukethe i-HfO2, okungelula ukuyihlukanisa. I-Zirconia ivame ukuhlanzwa ku-zirconium ore.

I-Zirconia inezinhlobo ezintathu zamakristalu: ikristalu ye-monoclinic esezingeni eliphansi (m-ZrO2), ikristalu ye-tetragonal esezingeni eliphakathi nendawo (t-ZrO2), i-cubic crystal yokushisa okuphezulu (c-ZrO2), amakristalu amathathu angenhla akhona ezibangeni zokushisa ezihlukene, futhi ingaguqulelwa komunye nomunye.

I-Zirconia ceramics uhlobo olusha lwe-ceramics yobuchwepheshe obuphezulu, ngaphezu kwamandla aphezulu, ukuqina, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali corrosion kanye nokuqina kwamakhemikhali aphezulu, ngesikhathi esifanayo nokumelana nokuqala, akukho ukuvikela isignali, ukusebenza okuhle kakhulu kokukhipha ukushisa. , ngenkathi ukusebenziseka, umphumela omuhle wokubukeka, ofanele ukukhiqizwa ngobuningi.

1. Iphuzu eliphezulu lokuncibilika

Indawo encibilikayo ye-zirconia ingu-2715 ℃, futhi indawo ephezulu yokuncibilika kanye nokungangeni kwamakhemikhali kwenza i-zirconia ibe into enhle yokuphikisa.

2. ubulukhuni obuphezulu, ukumelana okuhle kokugqoka

I-Zirconia Ceramics inobulukhuni obuphezulu nokumelana nokugqoka okungcono. Kusukela kudatha ethile, ubulukhuni be-Mohs be-zirconia ceramics cishe bungu-8.5, obuseduze kakhulu nobulukhuni be-Mohs besafire 9.

3. amandla nokuqina kukhulu uma kuqhathaniswa

I-Zirconia ceramics inamandla amakhulu (afinyelela ku-1500MPa).

4. i-conductivity ephansi yokushisa, i-coefficient ephansi yokwandisa

I-thermal conductivity ye-zirconia iyona ephansi kakhulu ezintweni ezivamile ze-ceramic (1.6-2.03W/ (mk)), futhi i-coefficient yokwandisa okushisayo iseduze naleyo yensimbi. Ngakho-ke, i-zirconia ceramics ifaneleka ezintweni zokwakha ze-ceramic.

5. ukusebenza kahle kagesi

I-dielectric constant ye-zirconia iphindwe izikhathi ezingu-3 kunesafire, isignali izwela kakhulu, futhi ifaneleka kakhulu ama-patches okuqashelwa kweminwe. Ngokusekelwe kumbono wokusebenza kahle kokuvikela, i-zirconia ceramics, njengento engeyona eyensimbi, ayinamthelela wokuvikela kumasignali kagesi, futhi ngeke ithinte ukwakheka kwe-antenna yangaphakathi, engahlanganiswa kalula futhi ivumelane nenkathi ye-5G.
