Abstract
This study aim to synthesis cordierite composites using new source of alumina from waste. The first groups were Sludge cake from aluminum scrap and dross recycling industry (Aw.), the other groups were commercial grade Alumina and other raw materials were kaolin, ball clay and talcum. The raw materials were ground, pressed, and sintered between 1200ฐC to 1325ฐC for 1 hour. The samples were investigated by XRD and thermal shock resistance tested, firing shrinkage, water absorption, and COE. The developed of crystal were studies by SEM and EDS. The COE of the sample W. synthesized at 1325ฐC were 3.95 ื 10-6ฐC-1 and the XRD analysis present that the main crystalline phase was cordierite. It can be concluded that the Aw. is a promising raw material and beneficial to Thai ceramics industry in terms of cost saving, competitiveness and environmental.
