POROUS CONDUCTIVE CERAMIC AND PREPARATION METHOD AND USE THEREOF
POROUS CONDUCTIVE CERAMIC AND PREPARATION METHOD AND USE The present invention belongs to the technical field of ceramic materials, and in particular, to a porous conductive ceramic and a preparation method and use thereof. The porous conductive ceramic is prepared from the following raw materials in parts by weight: alumina 50-65 parts; yttria stabilized zirconia powder 10-15 parts; silica 4-6 parts; a thickening agent 0.5-1 parts; and graphite 10-30 parts. In the present invention, dosages of the raw materials are optimized, and electrical and mechanical properties of the porous conductive ceramic are ensured through coordination of multiple components with specific content. In addition, the porous conductive ceramic is composed of simple raw materials for the preparation, helping to reduce costs and simplify the process. The preparation method of the porous conductive ceramic provided in the present invention is simple, can implement industrialization, and has an extremely high industrial application value and economic value. 0.7- dV/dlogR Pore Volume (mL/g) 'S 0.6 (D o 0.3 ) 0.2 -o0.1 I ' I II ' I 0 10000 20000 30000 40000 50000 Pore Radius (nm) 0.6- dV/dlogR Pore Volume (mUg) > 0.2 -) 0 10000 20000 30000 40000 50000 60000 70000 Pore Radius (nm)
