SUOYI High purity alumina polishing hmoov CP series alumina hmoov CAS 1344-28-1 yog siv rau polishing tsheb

Alumina yog ib qho ruaj khov oxide ntawm txhuas nrog cov tshuaj formula Al2O3. Nws tseem hu ua bauxite hauv mining, ceramics thiab cov ntaub ntawv tshawb fawb. Khoom: Cov khoom dawb uas nyuaj rau yaj hauv dej, tsis muaj ntxhiab, tsis qab, tsis tshua muaj zog, yooj yim absorbs noo noo tab sis tsis deliquesce (nws tsis nqus noo noo tom qab hlawv). Aluminium oxide yog ib qho amphoteric oxide (corundum yog α-puab thiab belongs rau hexagonal ze packing. Nws yog ib qho inert compound, me ntsis soluble hauv acid thiab alkali thiab resistant rau corrosion[1]). Nws tuaj yeem soluble hauv inorganic acids thiab alkaline daws, thiab yuav luag insoluble hauv dej. Thiab non-polar organic solvents; txheeb ze ntom ntom (d204) 4.0; melting point 2050 ° C. Cia: Khaws rau hauv lub thawv kaw thiab qhuav. Kev Siv: Siv los ua tshuaj ntsuam xyuas reagents, lub cev qhuav dej ntawm cov kuab tshuaj organic, adsorbents, organic tshuaj tiv thaiv catalysts, abrasives, polishing agents, raw khoom rau smelting aluminium, thiab cov ntaub ntawv refractory.
