I-Ultra High Precision Ceramic Material: i-silicon carbide, i-alumina, i-zirconia, i-silicon nitride

Emakethe, sijwayelene kakhulu nezinto ezikhethekile zobumba: i-silicon carbide, i-alumina, i-zirconia, i-silicon nitride.Isidingo semakethe esibanzi, hlaziya inzuzo yalezi zinhlobo eziningana zezinto.
I-Silicon carbide inezinzuzo zenani elishibhile, ukumelana nokuguguleka okuhle, amandla aphezulu, ukonakala okukhulu kulula ukwenza i-oxidize, kunzima ukucwilisa.I-Alumina iyona eshibhe kakhulu, futhi inqubo yokulungiselela impushana yezinto zokusetshenziswa ivuthwe kakhulu, kuyilapho i-zirconia ne-silicon nitrous oxide inobubi obusobala kulokhu, okuphinde kube ngenye yezinkinga ezivimbela ukuthuthukiswa kokubili kokugcina.I-silicon nitride, ikakhulukazi, ibiza kakhulu.
Mayelana nokusebenza, nakuba amandla, ukuqina kanye nezinye izakhiwo zemishini ye-silicon nitride ne-zirconia zingcono kakhulu kune-alumina, kubonakala sengathi ukusebenza kwezindleko kufanelekile, kodwa empeleni kunezinkinga eziningi.Okokuqala kusuka ku-zirconia, inokuqina okuphezulu, isizathu siwukuba khona kwe-stabilizer, kodwa ukuqina kwayo okuphezulu kuyazwela isikhathi, ayikwazi ukusetshenziswa emazingeni okushisa aphezulu kanye nokushisa kwekamelo isikhathi-sensitive kukhawulela kakhulu ukuthuthukiswa okungalungile kwe-oxidation, kufanele kube. yathi incane kakhulu kwezintathu emakethe.Futhi i-silicon nitride, iphinde ibe yi-ceramic ethandwayo eminyakeni engamashumi amabili edlule, amandla okushisa angagugi kanye nokunye ukusebenza okuphelele kuhle, kodwa ukusetshenziswa kwezinga lokushisa kuphansi kunalezi ezinye ezimbili;Inqubo yokulungiselela i-silicon nitride nayo iyinkimbinkimbi kakhulu kune-alumina, nakuba ukusetshenziswa kwesigaba se-silicon nitride kungcono kakhulu kune-zirconia, kodwa ukuqhathanisa okuphelele akukabi kuhle njenge-alumina.
Ukusebenza okungabizi, okuzinzile, ukuhlukahluka komkhiqizo wezitsha zobumba ze-alumina kwaba ukusetshenziswa kwasekuqaleni, futhi sekusetshenziswe izitsha zobumba ezikhethekile zamanje.
