%X The composition and crystal structure of the" White mud" ,or the Na-Al silicate slime in alumina production, is investigated by X-ray diffraction,IR spectra,differential thermal analysis, density detemination and chemical analysis concurrently. The chief phase, containing sodium aluminosilicate hydrate, has been identified to be hydroxy-sodalite crystals, usually having defect structure with vacancies of silicon atoms on the skeleton of sodalite lattice.
