Made porous ceramics based on clay and non-plastic aluminosilicate raw materials of Uzbekistan by slip casting. Molding was carried out using a blowing agent - technical foam and sawdust, stabilizing the structure, followed by firing at 1300 - 1350 ° C. The effect of various fillers on the physical and technical properties and microstructure of samples after sintering has been studied. It has been established that ceramics with a density of 700 - 900 kg / m 3 and a strength of 1.6 - 11.0 MPa can be obtained by foam technology with a mass content of foam from 15 to 25 & # 37 ;. Porous samples with the finest structure of grains and pores, obtained on the basis of Samarkand chamotte
