Khoom piav qhia
Bubble alumina yog ib hom tshiab ntawm cov khoom siv rwb thaiv tsev kub. Lawv yog ua los ntawm industrial alumina smelted thiab tshuab nyob rau hauv ib tug hluav taws xob rauv. Daim ntawv siv lead ua yog a-Al2O3 microcrystals. Siv alumina hollow npas ua lub cev tseem ceeb, nws tuaj yeem ua rau cov khoom ntawm ntau yam duab. Qhov siab tshaj plaws ua haujlwm kub yog 1800 degree. Lub zog txhua yam ntawm cov khoom yog siab, ob peb zaug ntawm cov khoom siv sib xws, thiab qhov ntim ntim tsuas yog ib nrab ntawm cov khoom corundum.
Bubble alumina tau dav siv nyob rau hauv high-temperature thiab ultra-high-temperature kilns xws li gasifiers nyob rau hauv petrochemical kev lag luam, carbon dub industrial reactors, thiab induction furnaces nyob rau hauv metallurgical kev lag luam, thiab tau ua tiav heev txaus siab zog-txuag teebmeem.
