    • There is provided a process for obtaining a cordierite honeycomb structural body with thin cell walls and no molding defects such as cell breakage or the like. Cell breakage is prevented by limiting the maximum particle size of the cordierite starting material powder to no greater than 85% of the slit width of the extrusion molding die so that the starting material particles will not clog inside the slits or the introduction port of the slits. As one cordierite starting material, talc with a mean particle size of 5 &mgr;m or greater is used to give a honeycomb structural body with a void volume of greater than 30%, for production of a honeycomb structural body, with good moldability, having a small thickness and a low heat capacity. It is preferred to add to the starting material at least a lubricant/humectant, a binder and/or a mixture of a water-soluble polyhydric alcohol derivative and a polyhydric alcohol.
    • 提供了一种获得具有细胞壁的堇青石蜂窝结构体并且没有诸如细胞破裂等的成型缺陷的方法。 通过将堇青石原料粉末的最大粒径限制在挤出成型模具的狭缝宽度的不大于85%的方式防止细胞破裂,使得原料颗粒不会堵塞狭缝或缝隙的引入口 。 作为一种堇青石原料,使用平均粒径为5μm以上的滑石,得到空孔体积大于30%的蜂窝结构体,制造蜂窝结构体,成形性好,成型性小 厚度和低热容量。 优选至少添加润滑剂/保湿剂,粘合剂和/或水溶性多元醇衍生物和多元醇的混合物的原料。
