Ua kom zoo dua cov alumina ceramic hmoov, qhov tsis xws luag ntau dua thiab ua haujlwm ntau dua nws yog .maj me me kuj tseem tuaj yeem tawg cov kev ntxhov siab los ntawm cov kab sib txawv ntawm cov sib xyaw ntawm corundum thiab iav theem ntawm thaj tsam lis, txo qhov kev pheej hmoo ntawm kev tawg.
Cov nplua nplej zoo yuav tseem tabkaum kev txhim kho ntawm microcrack, tsis yooj yim kom ua rau transgranular pob txha tawg, yog qhov zoo rau kev txhim kho pob txha tawv tawv.Thaum ntxiv, nws tseem tuaj yeem txhim kho qhov hnav tsis kam ntawm cov khoom siv.Yog li ntawd, nws tseem ceeb kom txo lub qhov me me ntawm Al 2 O 3 hmoov los npaj Al 2 O 3 cov khoom lag luam nrog kev ua tau zoo.Thaum tam sim no, muaj ob hom kev npaj los ua superfine nquag yooj yim sintered alumina hmoov: neeg kho tshuab txoj kev thiab tshuaj txujci.
Cov txheej txheem kho tshuab yog kho kom rov qab alumina hmoov raws li kev ua ntawm kev siv tshuab quab yuam sab nraud.Qhov feem ntau siv tshuab crushing yog pob sib tsoo, kev co sib tsoo, xuab zeb sib tsoo, roj sib tsoo, thiab lwm yam.
Kev ntub dej tshuaj yog qhov qauv tseem ceeb rau kev npaj ntawm ultrafine thiab siab purity hmoov, ntawm cov sol-gel txoj kev yog ntau paub tab.Wet tshuaj txoj kev tuaj yeem ncav nanoscale hmoov particle loj thiab nqaim particle loj faib, siab tshuaj purity, siv lead ua kev puas tsuaj, yog li tshuaj lom neeg hmoov saum npoo lub zog thiab cov tshuaj tiv thaiv reactive yog ntau dua li ntawm cov qauv siv tshuab, yog ua los ntawm super zoo hmoov ua cov khoom siv raw, tsis tsuas yog tuaj yeem txo qhov sintering kub ntawm alumina ceramics (txo), thiab tuaj yeem txais microcrystalline siab- lub zog aluminium cov khoom siv
