Alumina tej hub yooj yim nyob rau hauv cov khoom, paub tab nyob rau hauv kev tsim khoom siv tshuab, kuj raug nqi tsawg, zoo heev hauv hardness thiab coj kev tiv thaiv. Nws yog tsuas yog siv nyob rau hauv cov ris tsho-resistant ceramic kav dej ua ke ua cov khoom siv ntsug, thiab cua daj cua dub, uas tuaj yeem muab 10 zaug hnav tsis kam ntawm cov khoom siv nto. Hauv cov hnav-resistant cov ntaub ntawv, kev lag luam sib qhia ntawm alumina cov khoom tuaj yeem ncav cuag li 60% ~ 70%.
Qhov tseem ceeb tshaj plaws ntawm cov dab neeg sic ceramic yog zoo thermal poob siab tsis kam. Nyob rau hauv cov kev mob siab, cov khoom muaj cov cuab yeej siv tshuab hluav taws xob thiab tuaj yeem siv stables ntawm 1800 ℃ rau lub sijhawm ntev. Tus yam ntxwv thib ob yog tias cov khoom lag luam uas silicon tau siv los ua cov khoom loj nrog kev deformation me me. Nws yog tsuas yog siv nyob rau hauv preheatre dai daim ntawm kev lag luam cement, Kub Kub Cov Yeeb Yam Ceramic thiab High-kub conveying yeeb nkab kev lag luam. Piv txwv li, cov nozzles ntawm cov hlawv hauv cov nroj tsuag hluav taws xob thermal yog ua los ntawm cov yam ntxwv ntawm cov yam ntxwv ntawm qhov kub siab thiab hnav tsis kam. Cov txheej txheem Sintering ntawm Silicon Carbide Ceramics suav nrog cov tshuaj tiv thaiv sintering thiab messureless sintering. Tus nqi ntawm cov yeeb yam Sintering yog tsawg, cov khoom yog ntxhib, thiab qhov ntom ntawm cov khoom siv tshuab nqus khoom yog qhov siab. Lub hardness ntawm cov khoom yog zoo ib yam li ntawm alumina khoom, tab sis nws tus nqi yog ntau dua.
Cov khoom lag luam tiv thaiv ntawm cov ntaub ntawv zirconia ceramic zoo dua li ntawm cov ntaub ntawv loj. Tus nqi lag luam tam sim no ntawm zirconia hmoov yog kim heev, xws li cov ntaub ntawv kho hniav, cov pob txha khoom siv kho mob, thiab lwm yam khoom siv kho mob, thiab lwm yam.
