Utilization of aluminium buffing dust as a raw material for the production of mullite
Keywords:Mullite, Aluminium buffing dust, Refractory
AbstractAluminium buffing dust is a by-product from fine polishing process in aluminium part manufacture. Because of its high content of aluminium, alumina and silica, this waste could be used to prepare refractory mullite. Aluminium buffing dust and Ranong kaolin were mixed with the ratio of 100: 0 to 40:60 by ball milling. The batch mixtures were shaped by dry pressing. The green specimens were fired at temperature in the range of 1100-1400Â°C. The physical properties such as bulk density and water absorption were done by Archimedes principle. Phase analysis was observed by X-ray diffraction (XRD). Microstructural characterization was done by scanning electron microscopy (SEM). Modulus of rupture of the sintered samples were characterized by 3-point bending test. The results showed the specimen prepared from the batch mixture ratio of 60:40 and sintered at 1400Â°C has highest bulk density of 2.71 gÂ·cm-3 and bending strength of 60 MPa.
