Dab tsi yog oxide ceramics?

Oxide Ceramics yog ib chav kawm ntawm cov khoom siv ceramic siab heev nrog oxides ua cov khoom tseem ceeb.
Oxide ceramics muaj ntau yam zoo heev. Ua ntej, lawv feem ntau muaj siab tawv thiab lub zog thiab tuaj yeem tiv taus hnav thiab khawb. Piv txwv li, lub hardness ntawm alumina ceramics yog thib ob tsuas yog pob zeb diamond thiab yog dav siv nyob rau hauv mechanical processing, sib tsoo xov xwm thiab lwm yam teb. Qhov thib ob, oxide ceramics muaj qhov kub thiab txias tsis kam. Qee cov oxide ceramics xws li zirconium oxide thiab magnesium oxide tuaj yeem tswj cov qauv ruaj khov thiab kev ua haujlwm hauv qhov kub thiab txias, thiab tsim nyog rau kev siv kub xws li kub kub thiab lub cav qhov chaw. Tsis tas li ntawd, oxide ceramics kuj muaj tshuaj lom neeg ruaj khov thiab muaj zog tiv thaiv cov tshuaj xws li acids, alkalis, thiab ntsev. Lawv tuaj yeem siv rau cov khoom siv tiv thaiv corrosion hauv kev lag luam tshuaj thiab kev tiv thaiv ib puag ncig.
Muaj ntau hom oxide ceramics. Ntawm lawv, alumina ceramics yog hom oxide ceramics ntau tshaj plaws, nrog rau cov yam ntxwv ntawm siab hardness, siab zog, thiab siab rwb thaiv tsev, thiab yog dav siv nyob rau hauv electronics, machinery, tshuaj lom neeg kev lag luam thiab lwm yam kev lag luam. Zirconia ceramics muaj cov cuab yeej zoo heev thiab biocompatibility, thiab tau siv dav hauv cov cuab yeej txiav, cov cuab yeej kho mob thiab lwm yam. Magnesium oxide ceramics muaj qhov kub thiab txias tsis kam thiab rwb thaiv tsev, thiab feem ntau siv rau hauv qhov kub thiab txias, cov khoom siv hluav taws xob rwb thaiv tsev, thiab lwm yam. Tsis tas li ntawd, muaj ntau cov oxide ceramics xws li beryllium oxide ceramics thiab titanium oxide ceramics, txhua tus muaj cov khoom tshwj xeeb thiab daim ntawv thov teb.
Kev npaj cov txheej txheem ntawm oxide ceramics feem ntau suav nrog cov txheej txheem cov tshuaj tiv thaiv theem, cov txheej txheem ua kua theem cov tshuaj tiv thaiv thiab cov txheej txheem roj theem. Cov txheej txheem txheej txheem txheej txheem yog sib tov cov khoom siv oxide thiab sinter lawv ntawm qhov kub thiab txias los npaj oxide ceramics. Cov txheej txheem ua kua theem yog npaj cov oxide ceramic precursor los ntawm cov tshuaj tiv thaiv hauv cov tshuaj, thiab tom qab ntawd npaj cov oxide ceramic los ntawm ziab, sintering thiab lwm yam txheej txheem. Cov txheej txheem roj theem cov tshuaj tiv thaiv yog siv cov roj reactants los tiv thaiv qhov kub thiab txias los npaj oxide ceramics. Cov txheej txheem kev npaj sib txawv tuaj yeem npaj oxide ceramics nrog cov khoom sib txawv thiab microstructures.
Oxide ceramics tau dhau los ua ib qho ntawm cov lus qhia tseem ceeb hauv kev tshawb fawb ntawm cov ntaub ntawv niaj hnub nrog lawv cov kev ua tau zoo thiab kev siv dav dav. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tsis tu ncua, kev ua haujlwm ntawm oxide ceramics yuav txuas ntxiv txhim kho thiab cov peev txheej ntawm daim ntawv thov yuav txuas ntxiv.
