摘　　要：本文在保持显气孔率>35%的前提条件下,研究了等静压成型的成型压力对高温气固分离碳化硅多孔陶瓷支撑体的强度、孔隙率和过滤压降的影响,同时研究了造孔剂含量与所需成型压力的关系。结果表明,在满足孔隙率的前提下,随着造孔剂含量的变化,成型压力也需相应地变化。当造孔剂含量为3 wt%、成型压力为40 MPa时,成型后坯体的强度、烧成后制品的强度和过滤压降均较理想。In this paper, the effects of pressure on the strength, void fraction and pressure drop of high temperature gas solid separation silicon carbide porous ceramic supports were studied under the condition of keeping the porosity rate 〉 35%. The influence of pore forming agent content on the forming pressure and the pressure drop were studied. Through the research, it was found that when the pore forming agent content was 3 wt%, the pressure was 40 MPa, the strength and the pressure drop of product is ideal.
