ABSTRACT: To determine the optimum firing process, the influence of raw material, calcination temperature and mixing ratio on the packing density of muck based ceramics was studied. And then the apparent density, cylinder pressure, water absorption, loss and other physical properties were tested. The results show that: muck based ceramics for 700-900 density levels could be produced when the content of fly ash is 70%-83% and the content of fly ash is 17%-30%, the calcination temperature is 1170℃-1200℃, which is light brown with smooth surface and intact enamel layer, and the interior is loose and porous.
