Thaum lub sij hawm ntau lawm txheej txheem ntawmtabular alumina, tsis muaj additives ntxiv, yog li nws muaj siab purity thiab kuj loj grain hardness. Tabular alumina muaj thermal load zog, tsis tshua muaj thermal shrinkage, siab ceev thiab tsis tshua muaj huab cua permeability, thiab tshwj xeeb tshaj yog zoo hnav tsis kam. Muaj ntau qhov thaiv me me hauv cov nplej ntawm tabular corundum, yog li nws muaj qhov zoo thermal shock stability. Tabular alumina yog resistant rau tshuaj corrosion. Feem ntau alkalis thiab inorganic acids tsis cuam tshuam rau tabular corundum, tsuas yog hydrofluoric acid thiab phosphoric acid.
Qhov kev ua tau zoo no ua rau tabular alumina yog cov khoom siv zoo tshaj plaws rau cov khoom siv raw khoom refractory. Nws tuaj yeem siv los ua aggregate lossis ua ib qho ntxiv rau lwm cov khoom siv high-alumina amorphous refractory.
Tabular alumina tuaj yeem siv rau hauv qhov chaw uas fused corundum lossis dawb corundum yog siv los txhim kho kev ua haujlwm ntawm cov ntaub ntawv refractory.
Tabular alumina tuaj yeem siv rau hauv cov cuab yeej siv hluav taws xob hauv kev lag luam ceramic los txhim kho nws cov kev ua tau zoo. Piv txwv li, nws txhim kho cov thermal shock stability thiab deformation kuj ntawm ceramic rollers; thiab nce lub neej ntawm saggers thiab txee rau high-temperature ceramics.
Tsis tas li ntawd, cov phaj zoo li corundum kuj tseem siv tau los ua ib qho insulator thiab ua cov khoom siv catalyst rau cov kev kub ntxhov siab nrog cov porosity tsawg, siab zog thiab siab purity.
