Corundum Ntsia Saum
Qhov scientific lub npe yog alumina crucible. Feem ntau peb hu tus crucible nrog alumina cov ntsiab lus tshaj 95% raws li corundum crucible. 99.70% corundum crucible ntawm 1800 ℃, 1650 ℃ - 1700 ℃ muaj qhov kub zoo rwb thaiv tsev thiab cov tshuab muaj zog hauv oxidation thiab txo huab cua. High thermal conductivity thiab tsawg thermal nthuav. Nws tsis cuam tshuam nrog huab cua, dej vapor, hydrogen, carbon monoxide, thiab lwm yam saum toj no 1700 ℃. Qhov siab tshaj plaws kev pabcuam luv-ncua kub yog 1800 ℃.
Kev ntsuas ntawm 99.35% corundum ntawm 1750 ℃ 1600 ℃ - 1650 ℃ yog nyob rau hauv oxidizing thiab txo cov huab cua.
Lub 85.00% siab alumina crucible ntawm 1350 ℃ 1290 ℃ muaj qhov kub zoo rwb thaiv tsev thiab cov tshuab muaj zog hauv oxidation thiab txo huab cua. High thermal conductivity thiab tsawg thermal nthuav. Nws tsis' t hnov mob nrog huab cua, dej vapor, hydrogen, carbon monoxide, thiab lwm yam. Qhov siab tshaj plaws kev pabcuam luv-ncua kub yog 1400 ℃.
Cov khoom lag luam kom zoo dua
1) High hardness.
2) Lub tshav kub tsis kam: alumina ceramic muaj qhov zoo tshaj plaws stability, uas txhais tau hais tias nws yog dav siv nyob rau hauv qhov chaw uas tsis kam mus rau qhov kub siab yog qhov tseem ceeb.
3) Zoo hnav tsis kam: alumina ceramic yog cov khoom siv ntawm kev xaiv rau alumina coj qhov chaw.
4) Muaj hluav taws xob tsis kam tiv thaiv ntau: alumina yog cov khoom siv hluav taws xob tsis zoo.
5) zoo corrosion tsis kam: nws yog insoluble hauv dej thiab tsuas yog me ntsis soluble hauv kev muaj zog acid thiab alkaline. Tshuaj lom neeg ruaj khov ntawm alumina ua rau muaj kev tiv thaiv corrosion siab.
