Alumina ceramic yog qhov yooj yim hauv cov khoom siv, paub tab hauv kev tsim tshuab, tus nqi qis, zoo heev hauv hardness thiab hnav tsis kam. Nws yog tsuas yog siv nyob rau hauv hnav-resistant ceramic kav, hnav-resistant li qub li cov ntaub ntawv hauv ob sab phlu, thiab tseem yuav welded nrog studs los yog pasted rau lub puab phab ntsa ntawm cov khoom sib cais xws li industrial ntsug zeb, hmoov concentrator thiab cyclone, uas muaj peev xwm muab 10 lub sij hawm hnav tsis kam ntawm cov khoom nto. Hauv cov ntaub ntawv hnav-tiv taus, kev lag luam sib koom ntawm cov ntaub ntawv alumina tuaj yeem ncav cuag li 60% ~ 70%.
Cov yam ntxwv tseem ceeb tshaj plaws ntawm SiC ceramic khoom yog zoo thermal shock kuj. Nyob rau hauv qhov kub thiab txias, cov khoom muaj cov khoom siv kho tshuab ruaj khov thiab tuaj yeem siv tau ruaj khov ntawm 1800 ℃ rau lub sijhawm ntev. Qhov thib ob yam ntxwv yog tias cov khoom siv silicon carbide tuaj yeem siv los tsim cov khoom loj nrog me me deformation. Nws yog tsuas yog siv nyob rau hauv preheater dai daim ntawm cement kev lag luam, kub hnav-resistant ceramic nozzle, thee ntog yeeb nkab thiab high-temperature conveying yeeb nkab ntawm thermal fais fab kev lag luam. Piv txwv li, lub nozzles ntawm burners nyob rau hauv thermal fais fab nroj tsuag yog yeej ua los ntawm silicon carbide, thiab cov khoom muaj cov yam ntxwv ntawm kub kub kuj thiab hnav tsis kam. Cov txheej txheem sintering ntawm silicon carbide ceramics suav nrog cov tshuaj tiv thaiv sintering thiab pressureless sintering. Tus nqi ntawm cov tshuaj tiv thaiv sintering yog tsawg, cov khoom yog qhov ntxhib, thiab qhov ntom ntom ntawm cov khoom siv sintering yog qhov siab. Lub hardness ntawm cov khoom zoo ib yam li cov khoom ntawm alumina, tab sis nws tus nqi yog ntau dua.
Qhov khoov tsis kam ntawm zirconia ceramic cov ntaub ntawv yog zoo dua li cov ntaub ntawv nkig. Tus nqi lag luam tam sim no ntawm zirconia hmoov kuj tseem kim, uas yog siv rau hauv high-end teb, xws li cov ntaub ntawv kho hniav, pob txha pob txha, khoom siv kho mob, thiab lwm yam.
