10、refractory blocks and shapes into distinct classesbased on mineralogical composition.Such classes have histori-cally been useful for relating the defined types and classes withspecific industrial applications and for developing product orpurchasing specifications.5.Basis of Classification5.1 Fused a
11、lumina refractories are classified by the contentof soda,Na2O,as determined by chemical analysis and theresulting beta-(-)alumina(NaAl11O17)or beta-(-)alu-mina(NaMg2Al15O25)content as determined by quantitativeX-ray diffraction(XRD)or by quantitative image analysis ofrepresentative polished sections
12、.NOTE2Differential rates of solidification at the surface and theinterior of fusion-cast shapes result in different grain sizes.Likewise,thesegregation of one or more components may occur during solidification.Therefore,the most representative specimens are small,rapidly cooledladles or shapes(no di
