FIELD: ceramic material production. SUBSTANCE: sewage sediment of galvanic production is treated by dehydration, grinding and calcination in oxygen-less medium at 600-950 C and then mixed with clay. To charge ceramic mass composition the following components were added additionally, %: milled broken glass 15-33; abrasive flow sediment 15-30; broken plate 5-10, and plasticizing addition 0.5-1.0. Method is used for different plates production. EFFECT: enhanced utilization degree due to neutralization of toxic metals, improved ecology. 3 cl, 2 tbl
