Composite material mixed with Okinawa Kucha clay and the heat treated sludge which is an industry waste from sash factory was fabricated by compression molding and injection molding. These obtained results were as follows ; (1) In the compression molding with no use of binders, α alumina sludge particles inhibited the enlargement of numbers and size of pores caused by melting clay and the growing of pores when increasing the firing temperature. (2) The dimensional accuracy of fired body in injection molding was improved by increasing the content of sludge. (3) From the analysis of variance of bending strength, sludge content and injection pressure were specified as the significant factors on improvement of bending strength. The sludge particles perform the role of a reinforcement in the clay-sludge composite material. (4) By firing the body using micro wave sintering furnace, the sintering effect attributed to decrease the pores in the body comparing with the electric furnace. Especially, the bending strength improved drastically at the sludge content of 65%.
