A porous ceramic based on clay and nonplastic aluminosilicate raw material of Uzbekistan was prepared by slip casting. Molding was conducted using a foaming agent — technical foam and sawdust, which stabilized the structure, followed by firing at 1300 – 1350°C. The effect of different fillers on the physical and technical properties and microstructure of the samples was studied after sintering. It was determined that ceramic with density 700 – 900 kg/m³ and strength 1.6 – 11.0 MPa can be obtained by foam technology with foam content ranging from 15 to 25 wt.%. Porous samples with the finest grain and pore structure were obtained on the basis of Samarkand chamotte.

基于耐火粘土的高多孔材料的制备

通过滑模铸造制备了基于粘土和乌兹别克斯坦非塑料铝硅酸盐原料的多孔陶瓷。使用发泡剂进行模制，发泡剂是工业泡沫和木屑，可稳定结构，然后在1300 – 1350°C下烧制。烧结后研究了不同填料对样品的物理技术性能和微观结构的影响。经测定，可以通过泡沫技术获得密度为700 – 900 kg / m ³且强度为1.6 – 11.0 MPa的陶瓷，泡沫含量为15至25 wt。％。在撒马尔罕黏土的基础上获得了具有最佳晶粒和孔结构的多孔样品。
