Zusammenfassung:	The fabrication of ceramics incorporating aluminum waste comprises utilization of aluminum anodizing sludge and of slate cutting and polishing waste containing aluminum, in powder form. A 50 per cent sludge mix, pressed and sintered at 1250 degrees C gives ceramics of 7 per cent water absorption capacity and 27 MPa bend strength.
