Aluminium Oxide Alpha-theem 99.999% (Maim)
Txhuas OCIDE (AL2O3)Yog ib qho dawb lossis yuav luag tsis muaj xim crystalline, thiab cov tshuaj sib txuas ntawm txhuas thiab oxygen. Nws yog tsim los ntawm Bauxite thiab feem ntau hu ua Alumina thiab kuj tseem tau hu ua aloxide, aloxide, lossis alundum nyob ntawm cov ntaub ntawv tshwj xeeb lossis kev siv. AL2O3 muaj qhov tseem ceeb hauv nws cov kev siv los tsim cov hlau nplaum txhuas, vim tias muaj cov abrasive tshuav rau nws lub hardness, thiab raws li cov khoom siv refractory tiv rau nws lub siab yaj.
