摘　　要：Micro-honeycomb ceramics were successfully fabricated through brush-coating with cloth fabric as pore-forming agent. The influence of pore-forming agent and slurry’s moisture content on the micro-honeycomb ceramics was investigated. The results indicated that micro-honeycomb ceramics made from pore-forming agent cloth fabric with fibre diameter of 100 μm and slurry with 45% （mass fraction） moisture content have the porosity of 65% （volume fraction）, bending strength of 24.3 MPa, pore size of about 100 μm, cell wall thickness of about 50 μm and porosity of 1131 pore/cm2. It was suggested that the pore size and the porosity could be adjusted using the pore-forming agent and moisture content of the slurry respectively.采用刷涂法利用布纤维做造孔剂制备微蜂窝陶瓷,研究造孔剂种类和泥浆含水量的影响。结果表明:采用纤维直径为100μm的布做造孔剂和含水量为45%的泥浆制备的微蜂窝陶瓷孔隙率达到65%,抗弯强度为24.3MPa,孔径大约为100μm,孔壁厚度在50μm左右,孔数达到1310cm-2。通过改变造孔剂种类和泥浆含水量可以控制微蜂窝陶瓷的孔径和孔隙率的大小。
