Abstract
From the view point of more valuable use of clay and sludge as industry material, ceramics composite materials containing sludge particles of waste were fabricated by an injection molding process. The mechanical property and the quality of the mold parts were investigated by changing the firing instrument with electric furnace or microwave sintering. The experiment results show that microwave sintering instrument is superior to the the elecric furnace as a sintering instrument of the composite material using Kucha clay and α alumina structure sludge.
