Abstract

PURPOSE:To produce a porous sintered material by effectively utilizing wastes produced in a process for production of a pottery. CONSTITUTION:With 70 to 90wt.% waste of fired pottery crushed into 2 to 5mm size, 5 to 30wt.% waste of green ware for pottery is mixed and the resultant mixture is pressure molded and subsequently burned.
