【Abstract】 The ceramic industry slag,clay and solvent material were employed as raw material in this experiment.The raw materials were mixed and then sintered at 1 200 ℃ to obtain porous low density ceramics with good mechanical and thermal insulation properties.The appropriate material fabrication was discussed,and some properties were measured.The porous low density ceramics formed closed pores.The results are shown that the density of multi-pore ceramics is 4.6 g/cm3～6.5 g/cm3,compression strength is 9 MPa～12 MPa,the thermal conductivity is 0.121W/(m·K),noise insulation factor is 26 dB～32 dB and the average diameter of pores,which formed closed pores is 0.3mm.更多还原
